Code Issues Proposed changes

Change amphora logging to dedicated socket

Browse Source 
In some environments running older versions of gunicorn in the
amphora image, gunicorn can fail to start do to /dev/log socket
issues (timing, configuration, etc.).

This patch sets up a dedicated rsyslog socket /run/rsyslog/octavia/log
for gunicorn and haproxy to use. This should resolve any issues with
systemd overriding the /dev/log socket.

This also bumps the gunicorn minimum verison to 19.9.0.
