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

1e0a991fcd reduce memory capture in http logger
only capture the properties of 'req' that we need, to avoid leaking
the whole req object for responses that never call res.end()
