Vincent Breitmoser 6d7f0f8dd3 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.

Richard van der Hoff 88541f9009 Add a metric which increments when a request is received
It's useful to know when there are peaks in incoming requests - which isn't
quite the same as there being peaks in outgoing responses, due to the time
taken to handle requests.

Richard van der Hoff 19d274085f Make Counter render floats
Prometheus handles all metrics as floats, and sometimes we store non-integer
values in them (notably, durations in seconds), so let's render them as floats
too.

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

Erik Johnston 73c7112433 Change CacheMetrics to be quicker
We change it so that each cache has an individual CacheMetric, instead
of having one global CacheMetric. This means that when a cache tries to
increment a counter it does not need to go through so many indirections.

Erik Johnston 1f1dee94f6 Manually run GC on reactor tick.
This also adds a metric for amount of time spent in GC.
