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.

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.)

of having one global CacheMetric. This means that when a cache tries to
