Add support to enabling logging of security groups for
OpenStack Queens or later; this feature is enabled via
the neutron-api charm, with local charm configuration
options to allow control of rate and burst limits and to
set a local log output directory if require (allowing log
data to be written to a separate partition for example).
The feature is only compatible with the openvswitch firewall
driver and will not be enabled if this configuration option
is not set.
Basic deployment tests changes is included here since
nova-cloud-controller unit and relation was missing before,
and it leads to CI constantly failing.
