Also add a `default` implementation for `MonadQueryTags`.
This avoids a bunch of imports on `Hasura.GraphQL.Execute.Backend` which is a big module with lots of (transitive) dependencies.

This PR reverts the following two commits:
1. https://github.com/hasura/graphql-engine-mono/pull/8287
2. https://github.com/hasura/graphql-engine-mono/pull/8467
We are undoing a migration that was done on `hdb_catalog.event_log` table which was done in d4ae6a517da63f2f43567dc16fda135b3cd1d7e6 . And as such, users who were using event triggers on that version will come across the error:
```json
{"detail":{"info":{"code":"not-supported","error":"Expected source catalog version <= 3, but the current version is 4","path":"$"},"kind":"catalog_migrate"},"level":"error","timestamp":"2023-03-28T10:17:24.289+0530","type":"startup"}
{"code":"not-supported","error":"Expected source catalog version <= 3, but the current version is 4","path":"$"}
```
To fix these errors please run the following SQL on the source where event triggers were created on:
```
UPDATE hdb_catalog.hdb_source_catalog_version SET version = 3, upgraded_on= NOW();
ALTER table hdb_catalog.event_log ALTER COLUMN created_at SET DEFAULT NOW();
ALTER table hdb_catalog.event_invocation_logs ALTER COLUMN created_at SET DEFAULT NOW();
```

Ideally, we'd have one place for this.
I have also removed the pinned Cabal version because v3.10 should address the bug we were seeing in the v3.8 series.

## Description
This PR is a incremental step towards achieving the goal of #8344. It is a less ambitious version of #8484.
This PR removes all references to `HasServerConfigCtx` from the cache build and removes `ServerConfigCtx` from `CacheBuildParams`, making `ServerConfigCtx` an argument being passed around manually instead. This has several benefits: by making it an arrow argument, we now properly integrate the fields that change over time in the dependency framework, as they should be, and we can clean up some of the top-level app code.
## Implementation
In practice, this PR introduces a `HasServerConfigCtx` instance for `CacheRWT`, the monad we use to build the cache, so we can retrieve the `ServerConfigCtx` in the implementation of `CacheRWM`. This contributes to reducing the amount of `HasServerConfigCtx` in the code: we can remove `SchemaUpdateT` altogether, and we can remove the `HasServerConfigCtx` instance of `Handler`. This makes `HasServerConfigCtx` almost **an implementation detail of the Metadata API**.
This first step is enough to achieve the goal of #8344: we can now build the schema cache in the app monad, since we no longer rely on `HasServerConfigCtx` to build it.
## Drawbacks
This PR does not attempt to remove the use of `ServerConfigCtx` itself in the schema cache build: doing so would make this PR much much bigger. Ideally, to avoid having all the static fields given as arrow-ish arguments to the cache, we could depend on `HasAppEnv` in the cache build, and use `AppContext` as an arrow argument. But making the cache build depend on the full `AppEnv` and `AppContext` creates a lot of circular imports; and since removing `ServerConfigCtx` itself isn't required to achieve #8344, this PR keeps it wholesale and defers cleaning it to a future PR.
A negative consequence of this is that we need an `Eq` instance on `ServerConfigCtx`, and that instance is inelegant.
## Future work
There are several further steps we can take in parallel after this is merged. First, again, we can make a new version of #8344, removing `CacheBuild`, FINALLY. As for `ServerConfigCtx`, we can split it / rename it to make ad-hoc structures. If it turns out that `ServerConfigCtx` is only ever used for the schema cache build, we could split it between `CacheBuildEnv` and `CacheBuildContext`, which will be subsets of `AppEnv` and `AppContext`, avoiding import loops.

### Description
This PR is one more step towards #8344: it splits `initializeContext` into two parts: the first one builds the `AppEnv`, and the second builds the `AppContext` and its corresponding `AppStateRef`. Splitting it allows us to run the first schema cache build _in the app monad_, which was one of the steps required to remove `CacheBuild`, and ultimately to achieve #8344, which in turn is a blocker for several projects.

I am making this change for two reasons:
* We expect to upgrade to GHC 9.2.7 imminently, which is not available on the nixos-22.11 branch.
* We need to upgrade unixODBC, which has stagnated on nixos-22.11.
While we expect a new NixOS release in a month or two, we can't really afford to wait that long. In addition, we might need to upgrade GHC again soon after that.
I removed `hpack` because we don't actually use it any more.

### Description
This PR is the logical continuation of #8343 and #8357, and replaces both.
One core problem that this PR addresses: we had to create temporary a `HTTP.Manager` to initialize both the OSS and the Pro app: a manager is required to build the schema cache, but the dynamic TLS allow list is read from the schema cache... This PR solves this, by introducing the `TLSAllowListRef`, based on @abooij 's idea: it allows us to create a valid `HTTP.Manager` as soon as we have the metadata list, and then update the ref at a later point to make it point to the schema cache, allowing us to only build one and only one `HTTP.Manager`.
This paves the way towards building the schema cache _in the app monad_ and deprecating `CacheBuild`. Towards this, and also to clean the code, this PR also splits the catalog migration and the first schema cache build into two distinct functions. This doesn't result in a change of behaviour, as the transaction to update the catalog would always be done before attempting to build the schema cache.

### Description
This small PR is on top of #8440. It continues the cleanup of `Hasura/App` by grouping together all instances on the app monad, renaming the app monad, and removing its `m` parameter.

### Description
As part of another project (the continuation of #8421), i have started a cleanup of `Hasura.App`, focusing on deleting old code and grouping together things that belong together. This quickly grew into a refactor of `GlobalCtx`, now renamed into `BasicConnectionInfo`. This small refactor adds comments, and aims at making clear what the purpose of those types and functions is.
Furthermore, it also changes the way the default postgres connection info is created, by making that part of the process of creating the `BasicConnectionInfo`, to deduplicate similar effort across different files.
This is expected to be a no-op.

### Description
This PR continues some of the work done in #8392, and makes use of `HasAppEnv` to reduce the amount of explicit env passing in init functions, including removing it from the setup hook.

### Description
This small PR removes `ExecutionCtx`: it was only used as a `Reader` argument for `runGQ`, and two of its wrappers. Explicit argument passing removes one additional small record, and one more `runReaderT`.

GitOrigin-RevId: cdf65f643283be37d493d483d46a586f0f9ef885
## Description
This PR does several different things that happen to overlap; the most important being:
- it removes `RunT`: it was redundant in places where we already had `Handler`, and only used in one other place, `SchemaUpdate`, for which a local `SchemaUpdateT` is more than enough;
- it reduces the number of places where we create a `ServerConfigCtx`, since now `HasServerConfigCtx` can be implemented directly by `SchemaUpdateT` and `Handler` based on the full `AppContext`;
- it drastically reduces the number of arguments we pass around in the app init code, by introducing `HasAppEnv`;
- it simplifies `HandlerCtx` to reduce duplication
In doing so, this changes paves the way towards removing `ServerConfigCtx`, since there are only very few places where we construct it: we can now introduce smaller classes than `HasServerConfigCtx`, that expose only a relevant subset of fields, and implement them where we now implement `HasServerConfigCtx`.
This PR is loosely based on ideas in #8337, that are no longer applicable due to the changes introduced in #8159. A challenge of this PR was the postgres tests, which were running in `PGMetadataStorageAppT CacheBuild` 🙀

- Delete some dead code (methods and types)
- Delete some `INLINE` pragmas that are unlikely to have a big effect
- Monomorphize Postgres `LISTEN` code to avoid effect juggling
- Generalize some methods in `pg-client` so that others can be simplified
- Handle errors differently for `TxET` to deduplicate code
- Use `hoist` instead of specialized combinators such as `mapActionT`

This PR is on top of #7789.
### Description
This PR entirely rewrites the API of the Tracing library, to make `interpTraceT` a thing of the past. Before this change, we ran traces by sticking a `TraceT` on top of whatever we were doing. This had several major drawbacks:
- we were carrying a bunch of `TraceT` across the codebase, and the entire codebase had to know about it
- we needed to carry a second class constraint around (`HasReporterM`) to be able to run all of those traces
- we kept having to do stack rewriting with `interpTraceT`, which went from inconvenient to horrible
- we had to declare several behavioral instances on `TraceT m`
This PR rewrite all of `Tracing` using a more conventional model: there is ONE `TraceT` at the bottom of the stack, and there is an associated class constraint `MonadTrace`: any part of the code that happens to satisfy `MonadTrace` is able to create new traces. We NEVER have to do stack rewriting, `interpTraceT` is gone, and `TraceT` and `Reporter` become implementation details that 99% of the code is blissfully unaware of: code that needs to do tracing only needs to declare that the monad in which it operates implements `MonadTrace`.
In doing so, this PR revealed **several bugs in the codebase**: places where we were expecting to trace something, but due to the default instance of `HasReporterM IO` we would actually not do anything. This PR also splits the code of `Tracing` in more byte-sized modules, with the goal of potentially moving to `server/lib` down the line.
### Remaining work
This PR is a draft; what's left to do is:
- [x] make Pro compile; i haven't updated `HasuraPro/Main` yet
- [x] document Tracing by writing a note that explains how to use the library, and the meaning of "reporter", "trace" and "span", as well as the pitfalls
- [x] discuss some of the trade-offs in the implementation, which is why i'm opening this PR already despite it not fully building yet
- [x] it depends on #7789 being merged first
