After, on my 8-core machine, for a full rebuild of just the 360 oss
modules, I get build times:
unoptimized: 2:45 (previously: 3:37)
optimized: 9:30 (previously: 13:35)
## Should this live in the repo?
Arguably this should go in a user's `~/.cabal/config`, but I think if merging this improves things for a decent number of devs it's worth having (rather than another thing to document in onboarding docs)
Downsides:
- this might override someone's settings that work even better for them?
- A few folks might have systems not powerful enough for these to be appropriate?
of course some people use their own cabal.project.local anyway

This excercises a different code path from regular queries and is
pretty slow. Motivated by https://github.com/hasura/graphql-engine-mono/pull/2835
We may need to break chinook up into two sets if it keeps growing or
becomes a bottleneck, but do that later.

This PR simplifies the types that represent a remote relationship in IR so that they can be reused in other parts (in remote schema types) which could have remote relationships.
The comments on the PR explain the main changes.

# Description
The tests were only being run with fully qualified postgresql and
mssql connection env vars anyhow. Makes it a bit simpler to run the
tests.
- the test suite now requires only plain connection strings as
`HASURA_GRAPHQL_DATABASE_URL` (postgres) or
`HASURA_MSSQL_CONN_STR` (mssql)
- update `CONTRIBUTING.md` for this change, and make it
generally a bit less inaccurate

GraphQL types can refer to each other in a circular way. The PDV framework used to use values of type `Unique` to recognize two fragments of GraphQL schema as being the same instance. Internally, this is based on `Data.Unique` from the `base` package, which simply increases a counter on every creation of a `Unique` object.
**NB**: The `Unique` values are _not_ used for knot tying the schema combinators themselves (i.e. `Parser`s). The knot tying for `Parser`s is purely based on keys provided to `memoizeOn`. The `Unique` values are _only_ used to recognize two pieces of GraphQL _schema_ as being identical. Originally, the idea was that this would help us with a perfectly correct identification of GraphQL types. But this fully correct equality checking of GraphQL types was never implemented, and does not seem to be necessary to prevent bugs.
Specifically, these `Unique` values are stored as part of `data Definition a`, which specifies a part of our internal abstract syntax tree for the GraphQL types that we expose. The `Unique` values get initialized by the `SchemaT` effect.
In #2894 and #2895, we are experimenting with how (parts of) the GraphQL types can be hidden behind certain permission predicates. This would allow a single GraphQL schema in memory to serve all roles, implementing #2711. The permission predicates get evaluated at query parsing time when we know what role is doing a certain request, thus outputting the correct GraphQL types for that role.
If the approach of #2895 is followed, then the `Definition` objects, and thus the `Unique` values, would be hidden behind the permission predicates. Since the permission predicates are evaluated only after the schema is already supposed to be built, this means that the permission predicates would prevent us from initializing the `Unique` values, rendering them useless.
The simplest remedy to this is to remove our usage of `Unique` altogether from the GraphQL schema and schema combinators. It doesn't serve a functional purpose, doesn't prevent bugs, and requires extra bookkeeping.

### Description
This PR fixes two small issues with the `dev.sh` script:
- when running the script without a specific test flag (`./scripts/dev.sh test`), we would start some of the containers more than once; this PR fixes this by checking whether the container is already running before starting it
- we were still doing some bigquery setup in the main code, despite that setup being already done in `parse-pytest-backend`, which would result in biquery setup errors even when testing non-bigquery backends; this PR just deletes the redundant line.

### Description
This PR changes the internal representation of a parsed remote schema. We were still using a list of type definitions, meaning every time we were doing a type lookup we had to iterate through a linked list! 🙀 It was very noticeable on large schemas, that need to do a lot of lookups. This PR consequently changes the internal representation to a HashMap. Building the OneGraph schema on my machine now takes **23 seconds**, compared to **367 seconds** before this patch.
Some important points:
- ~~this PR removes a check for type duplication in remote schemas; it's unclear to me whether that's something we need to add back or not~~ (no longer true)
- this PR makes it obvious that we do not distinguish between "this remote schema is missing type X" and "this remote schema expects type X to be an object, but it's a scalar"; this PR doesn't change anything about it, but adds a comment where we could surface that error (see [2991](https://github.com/hasura/graphql-engine-mono/issues/2991))

Source typename customization (hasura/graphql-engine@aac64f2c81) introduced a mechanism to change certain names in the GraphQL schema that is exposed. In particular it allows last-minute modification of:
1. the names of some types, and
2. the names of some root fields.
The above two items are assigned distinct customization algorithms, and at times both algorithms are in scope. So a need to distinguish them is needed.
In the original design, this was addressed by introducing a newtype wrapper `Typename` around GraphQL `Name`s, dedicated to the names of types. However, in the majority of the codebase, type names are also represented by `Name`. For this reason, it was unavoidable to allow for easy conversion. This was supported by a `HasName Typename` instance, as well as by publishing the constructors of `Typename`.
This means that the type safety that newtypes can add is lost. In particular, it is now very easy to confuse type name customization with root field name customization.
This refactors the above design by instead introducing newtypes around the customization operations:
```haskell
newtype MkTypename = MkTypename {runMkTypename :: Name -> Name}
deriving (Semigroup, Monoid) via (Endo Name)
newtype MkRootFieldName = MkRootFieldName {runMkRootFieldName :: Name -> Name}
deriving (Semigroup, Monoid) via (Endo Name)
```
The `Monoid` instance allows easy composition of customization operations, piggybacking off of the type of `Endo`maps.
This design allows safe co-existence of the two customization algorithms, while avoiding the syntactic overhead of packing and unpacking newtypes.
