9a96e7d165 server: parallelize buildGQLContext to improve replace_metadata perfo…
…rmance

It makes sense to try to utilize multiple threads for metadata
operations since we expect them to come one at a time (and likely at
lower load periods anyway).

As noted, although we build roles in parallel now, the admin role is
still a bottleneck. For replace_metadata on huge_schema, on my machine
I get:

  BEFORE: 22.7 sec
   AFTER: 13.5 sec

11a454c2d6 server, pro: actually reformat the code-base using ormolu
This commit applies ormolu to the whole Haskell code base by running `make format`.

For in-flight branches, simply merging changes from `main` will result in merge conflicts.
To avoid this, update your branch using the following instructions. Replace `<format-commit>`
by the hash of *this* commit.

$ git checkout my-feature-branch
$ git merge <format-commit>^    # and resolve conflicts normally
$ make format
$ git commit -a -m "reformat with ormolu"
$ git merge -s ours post-ormolu

More robust forking, exception safety. Closes #3768 (#3860)
This is the result of a general audit of how we fork threads, with a
detour into how we're using mutable state especially in websocket
codepaths, making more robust to async exceptions and exceptions
resulting from bugs.

Some highlights:
- use a wrapper around 'immortal' so threads that die due to bugs are
  restarted, and log the error
- use 'withAsync' some places
- use bracket a few places where we might break invariants
- log some codepaths that represent bugs
- export UnstructuredLog for ad hoc logging (the alternative is we
  continue not logging useful stuff)

I had to timebox this. There are a few TODOs I didn't want to address.
And we'll wait until this is merged to attempt #3705 for
Control.Concurrent.Extended

58ef316118 Add request timings and count histograms to telemetry. Closes #3552
We upload a set of accumulating timers and counters to track service
time for different types of operations, across several dimensions (e.g.
did we hit the plan cache, was a remote involved, etc.)

Also...

Standardize on DiffTime as a standard duration type, and try to use it
consistently.

See discussion here:
https://github.com/hasura/graphql-engine/pull/3584#pullrequestreview-340679369

It should be possible to overwrite that module so the new threadDelay
sticks per the pattern in #3705 blocked on #3558

Rename the Control.Concurrent.Extended.threadDelay to `sleep` since a
naive use with a literal argument would be very bad!

We catch a bug in 'computeTimeDiff'.

Add convenient 'Read' instances to the time unit utility types. Make
'Second' a newtype to support this.
