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.

Many tasks that use Docker have become specified already, but
not all. This change ensures all tasks that use the following
modules have become:
* kolla_docker
* kolla_ceph_keyring
* kolla_toolbox
* kolla_container_facts
It also adds become for 'command' tasks that use docker CLI.

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.

A small number of services set the recurse flag when they create
their config directory. This can change permission of files within
the directory, which are later set back to the original state. The
side effect is that the service is then restarted, even though the
net change to the config files amounts to nothing. The expected
behaviour is that a service only restarts if the config *has*
changed. This patch fixes this issue.
