Include coarse CPU and Memory use in stats callbacks.

This requires the psutil module, and is still opt-in based on the report_stats
config option.

Upgrading to $NEXT_VERSION
====================
This release expands the anonymous usage stats sent if the opt-in
``report_stats`` configuration is set to ``true``. We now capture RSS memory
and cpu use at a very coarse level. This requires administrators to install
the optional ``psutil`` python module.
We would appreciate it if you could assist by ensuring this module is available
and ``report_stats`` is enabled. This will let us see if performance changes to
synapse are having an impact to the general community.
Upgrading to v0.15.0
====================
