4a92be80ea Send HTTP request size metric 
The metric is a "summary" called http_request_size_bytes.

03e81153db avoid step effects in summary metrics 
reduce the window size from 10 minutes to 1 minute,  so that short
spikes do not cause a 10 minute long "table" graph.

166211b278 Stackdriver logging 
When the environment variable STACKDRIVER_LOGGING is set to true, send
request logs in a format that Stackdriver knows how to interpret. Also,
set the log level accordint to the status code. 4xx responses are logged
as warnings and 5xx responses are logged as errors.

07e4eb4dfb Add mechanism to expire old prometheus metrics 
Adds a wrapper around the prometheus client, which keeps track of the
last time a metrics was accessed, and removes old ones once they have
not been accessed for a period of time.

8db30020ae Monitor event loop by looking for skew 
If we monitor with setImmediate, we miss big blocking loops. For example,
suppose we have 1000 1ms loops then a single bad 1000ms loop. setImmediate
will only be called at the right time 1/1000 of the time (it has to be the
loop just before the bad one). So this monitoring method gives a good average
if the std dev is low, but doesn't pick up spikes.

Instead, we can monitor the skew from the expected time between setIntervals.
In the case above, with a setInterval for 1000ms, we will pick up a skew
proportional to the amount of time that it overlaps the bad loop. So 50%
change of picking up skew > 500ms, and thus getting a good sense of any
spikes.

9329249bc9 Revert "reduce memory capture in http logger" 
This reverts commit fc2e043b20204e04f240814d4efc05762db7df96.

Had to revert this because req.route.path is not set until a matching
route has been hit, so it was always null inside res.end meaning
statsd data was never sent over.

This commit did not actually stop the memory leak so reverting it
has not short term repocusion
