## Description
This PR updates the JWK refresh thread to poll every second instead of the previous behaviour where the thread used to sleep based on the expiry time in `Cache-Control`/`Expires` response headers.
## Motivation
As a part of dynamically updating environment variables on cloud without restart the user projects, we want to implement a mechanism which makes HGE aware of any changes in the user configuration by updating a shared variable data type which can be accessed by relevant threads/core functionality before their execution.
The above updates requires us to make the threads polling in nature such that before executing their code, any change in the user config is captured and the appropriate behaviour is channelised. In the case of JWK updating thread, the thread used to sleep for the time as mentioned in the `Cache-Control` or `Expires` headers which make the thread unware of any new changes in the user config in that period of time, hence requiring a restart to propogate the new changes.
To solve this problem we have now updated the JWK update thread to poll every second for change in `AuthMode`(from a shared variable in subsequent changes to implement the dynamic env var update feature) and update the JWK accordingly such that it does not use any stale configurations and works without HGE restart.

https://hasurahq.atlassian.net/browse/GS-300
### Solution and Design
- We store the expiry time in the `JWTCtx`
- On every poll check whether the current time exceeds the expiry time, in which case we call the JWK url to fetch the new JWK and expiry.

We currently let the garbage collector and/or the operating system clean up our mess. This is mostly fine in production (kind of) but a problem when we want to start many HGE servers in parallel for testing purposes.
Shutting them down should, in theory, ease the load.
There is more work to be done in the API test suite before this is very helpful. Right now the test suite actually runs the finalizers on the server context straight away and then uses the leaked resources. As there's no way to actually "close" a connection pool, it keeps working regardless. If we wanted to be strict about this we might want to add a "closed" flag to `Data.Pool` which would cause an exception on `withResource` after closing it.

Mostly trying to avoid tricky `Arrows` syntax, and unnecessary use of the `Hasura.Incremental` framework.

This upgrades the version of Ormolu required by the HGE repository to v0.5.0.1, and reformats all code accordingly.
Ormolu v0.5 reformats code that uses infix operators. This is mostly useful, adding newlines and indentation to make it clear which operators are applied first, but in some cases, it's unpleasant. To make this easier on the eyes, I had to do the following:
* Add a few fixity declarations (search for `infix`)
* Add parentheses to make precedence clear, allowing Ormolu to keep everything on one line
* Rename `relevantEq` to `(==~)` in #6651 and set it to `infix 4`
* Add a few _.ormolu_ files (thanks to @hallettj for helping me get started), mostly for Autodocodec operators that don't have explicit fixity declarations
In general, I think these changes are quite reasonable. They mostly affect indentation.

- Remove `onJust` in favor of the more general `for_`
- Remove `withJust` which was used only once
- Remove `hashNub` in favor of `Ord`-based `uniques`
- Simplify some of the implementations in `Hasura.Prelude`
- Add `hlint` hint from `maybe True` to `all`, and `maybe False` to `any`

Result of executing the following commands:
```shell
# replace "as Q" imports with "as PG" (in retrospect this didn't need a regex)
git grep -lE 'as Q($|[^a-zA-Z])' -- '*.hs' | xargs sed -i -E 's/as Q($|[^a-zA-Z])/as PG\1/'
# replace " Q." with " PG."
git grep -lE ' Q\.' -- '*.hs' | xargs sed -i 's/ Q\./ PG./g'
# replace "(Q." with "(PG."
git grep -lE '\(Q\.' -- '*.hs' | xargs sed -i 's/(Q\./(PG./g'
# ditto, but for [, |, { and !
git grep -lE '\[Q\.' -- '*.hs' | xargs sed -i 's/\[Q\./\[PG./g'
git grep -l '|Q\.' -- '*.hs' | xargs sed -i 's/|Q\./|PG./g'
git grep -l '{Q\.' -- '*.hs' | xargs sed -i 's/{Q\./{PG./g'
git grep -l '!Q\.' -- '*.hs' | xargs sed -i 's/!Q\./!PG./g'
```
(Doing the `grep -l` before the `sed`, instead of `sed` on the entire codebase, reduces the number of `mtime` updates, and so reduces how many times a file gets recompiled while checking intermediate results.)
Finally, I manually removed a broken and unused `Arbitrary` instance in `Hasura.RQL.Network`. (It used an `import Test.QuickCheck.Arbitrary as Q` statement, which was erroneously caught by the first find-replace command.)
After this PR, `Q` is no longer used as an import qualifier. That was not the goal of this PR, but perhaps it's a useful fact for future efforts.

## Description ✍️
This PR fixes the config status update when the `Service configured successfully` message is written before the server is actually spawned. Now the status is updated only when the server is spawned successfully. To be specific, this change posts the status closer to where we log `starting API server`.
### Related Issues ✍
#2751
### Solution and Design ✍
We update the status inside `runHGEServer` function. This helps in adding the message only when the server is started. If any exception is thrown before the server is spawned, only that message is written to `config_status` table instead of the `Service configured successfully` message.
## Affected components ✍️
- ✅ Server

We only use these `Show` instances in error messages (where we call
`show` explicitly anyway) and test cases (in which Hspec requires `Show
a` for any `a` in an assertion).
This removes the instance in favor of a custom `showQErr` function
(which serializes the error to JSON). It is then used in certain error
message production which previously called `show` on a `QErr`.
There are two places where we serialize a QErr and then construct a new
QErr from the resulting string. Instead, we modify the existing QErr to
add extra information.
An orphan `Show QErr` instance is retained for tests so that we can have
nice test failure messages.
This is preparation for future changes in which the error message within
`QErr` will not be exposed directly, and therefore will not have a
`Show` instance. That said, it feels like a sensible kind of cleanup
anyway.
