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.

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.

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.

Don't disable GC when running on PyPy
...
PyPy's incminimark GC can't be triggered manually. From what I observed
there are no obvious issues with just letting it run normally. And
unlike CPython, it actually returns unused RAM to the system.

Make Counter render floats

Prometheus handles all metrics as floats, and sometimes we store non-integer

too.
(Note that the standard client libraries also treat Counters as floats.)
