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.

780857fb19 Switch to a CPS implementation of Rule 
This is significantly more performance, even without specialization,
which dramatically improves compile times.

c322e8a5d4 Use a significantly more efficient table_info_agg view 
Also, use the view in Schema.Diff to share some more logic.

ed26da59a6 Add support for GraphQL enum types via enum table references 
These changes also add a new type, PGColumnType, between PGColInfo and
PGScalarType, and they process PGRawColumnType values into PGColumnType
values during schema cache generation.
