Update docs to generate Guru Meditation Report

Guru Meditation Reports (GMR) code in oslo.reports was recently updated
to expect SIGUSR2 as opposed to SIGUSR1, because it is reserved by
Apache 'mod_wsgi' for its own use.

Signal was changed and merged in change:
I9d3b6079ba2cca41fe4723723a6f80b2c3c0b9c0

Generating a GMR
----------------
A *GMR* can be generated by sending the *USR1* signal to any Cinder process
A *GMR* can be generated by sending the *USR2* signal to any Cinder process
with support (see below).
The *GMR* will then be outputted standard error for that particular process.
For example, suppose that ``cinder-api`` has process id ``8675``, and was run
with ``2>/var/log/cinder/cinder-api-err.log``.
Then, ``kill -USR1 8675`` will trigger the Guru Meditation report to be printed
Then, ``kill -USR2 8675`` will trigger the Guru Meditation report to be printed
to ``/var/log/cinder/cinder-api-err.log``.
