Drop support for ancient prometheus_client (#8426) 
Drop compatibility hacks for prometheus-client pre 0.4.0. Debian stretch and
Fedora 31 both have newer versions, so hopefully this will be ok.

Use slots in attrs classes where possible (#8296) 
slots use less memory (and attribute access is faster) while slightly
limiting the flexibility of the class attributes. This focuses on objects
which are instantiated "often" and for short periods of time.

Set Content-Length for Metrics requests (#7730) 
HTTP requires the response to contain a Content-Length header unless chunked encoding is being used.
Prometheus metrics endpoint did not set this, causing software such as prometheus-proxy to not be able to scrape synapse for metrics.

synapse.metrics: implement detailed memory usage reporting on PyPy (#7536) 
PyPy's gc.get_stats() returns an object containing detailed allocator statistics
which could be beneficial to collect as metrics.

367158a609 Add wrap_as_background_process decorator. 
This does the same thing as `run_as_background_process` but means we
don't need to create superfluous functions.

03751a6420 Fix some looping_call calls which were broken in #3604 
It turns out that looping_call does check the deferred returned by its
callback, and (at least in the case of client_ips), we were relying on this,
and I broke it in #3604.

Update run_as_background_process to return the deferred, and make sure we
return it to clock.looping_call.

6e3fc657b4 Resource tracking for background processes 
This introduces a mechanism for tracking resource usage by background
processes, along with an example of how it will be used.

This will help address #3518, but more importantly will give us better insights
into things which are happening but not being shown up by the request metrics.

We *could* do this with Measure blocks, but:
 - I think having them pulled out as a completely separate metric class will
   make it easier to distinguish top-level processes from those which are
   nested.

 - I want to be able to report on in-flight background processes, and I don't
   think we want to do this for *all* Measure blocks.
