Refactor logcontext resource usage tracking (#3501)
Factor out the resource usage tracking out to a separate object, which can be
passed around and copied independently of the logcontext itself.

otherwise we explode with:

...where the logger apparently recurses whilst trying to log the error, hitting the
maximum recursion depth and killing everything badly.

b088aafcae Log number of events fetched from DB
When we finish processing a request, log the number of events we fetched from
the database to handle it.

[I'm trying to figure out which requests are responsible for large amounts of
event cache churn. It may turn out to be more helpful to add counts to the
prometheus per-request/block metrics, but that is an extension to this code
anyway.]

dfa70adc33 Add in flight request metrics
This tracks CPU and DB usage while requests are in flight, rather than
when we write the response.

318711e139 Set Server header in SynapseRequest
(instead of everywhere that writes a response. Or rather, the subset of places
which write responses where we haven't forgotten it).

This also means that we don't have to have the mysterious version_string
attribute in anything with a request handler.

Unfortunately it does mean that we have to pass the version string wherever we
instantiate a SynapseSite, which has been c&ped 150 times, but that is code
that ought to be cleaned up anyway really.

c6f730282c Move RequestMetrics handling into SynapseRequest.processing()
It fits quite nicely here, and opens the path to getting rid of the
"include_metrics" mess.

3d12d97415 Track DB scheduling delay per-request
For each request, track the amount of time spent waiting for a db
connection. This entails adding it to the LoggingContext and we may as well add
metrics for it while we are passing.
