Currently, we have a lot of logic for checking if a handler should run,
depending on whether config files have changed and whether the
container configuration has changed. As rm_work pointed out during
the recent haproxy refactor, these conditionals are typically
unnecessary - we can rely on Ansible's handler notification system
to only trigger handlers when they need to run. This removes a lot
of error prone code.
This patch removes conditional handler logic for all services. It is
important to ensure that we no longer trigger handlers when unnecessary,
because without these checks in place it will trigger a restart of the
containers.

With this change, an operator may be able to stop a
service container without stopping all services in a host.
This change is the starting point to start
fast-forward upgrades support.
In next changes new flags will be introducced to disable
stop dataplane services during upgrades.

Certain services such as Murano and trove require access to a rabbitmq
instance from tenant networks. [0]
Exposing the internal rabbitmq to end users is a security hole, hence
there are two options, 1) use vhosts in the existing rabbitmq, or two a
separate rabbitmq instances. Given the importance of rabbitmq to the
OpenStack deployment, we have decided to go with a separate instance.
Refer to [1] for more detail on the various options.
This change makes the rabbitmq role generic so that it can be reused, in
this case to start 'outward_rabbitmq'. It needs to be exposed via
haproxy both for network isolation and also because this is what Murano
configuration requires.
Follow on patches will be added to add a vhost in this outward instance
for Murano and other services which require access.

Influxdb is standalone deployed by kolla-ansible,
The cluster mode is charged now.
Previously configured, each telegraf monitors all influxdb.
If the telegraf is more, It is a disaster to influxdb.
So, telegraf should monitor influxdb deployed on the same server.
