We use the wsrep_notify.sh script to notify changes in Galera cluster
membership to haproxy. When xtrabackup was used for the state transfer,
nodes in the Donor state would be included in the backend pool. However,
since the switch to mariabackup in the Stein cycle, we now remove nodes
in the Donor state from the backend pool.

This change ensures that nodes in the Donor state are included in the
backend pool when the SST method is either xtrabackup or mariabackup.

The version_compare filter was renamed to version and changed to be a
test in 2.5. The old filter was removed in 2.9.

Starting with the Train release, kolla_ansible (the package) must be
available in the PYTHONPATH to run most playbooks.
It is documented.
This change makes the error message friendlier.

cinder-backup[1] does not include an lvm driver, we could use posix
filesystem driver - but it's not supported in kolla-ansible currently.

Due to a Docker bug [1] we cannot use Docker to send
SIGHUP to the container because it will mark it as
stopped.
This patch sends the signal directly to the process,
bypassing Docker.

'changed_when: false' is also removed from the
relevant task as it definitely changes the state.
In the future we could do the refresh only if
there really is a need for another one.

If docker_storage_driver is set in globals.yml, then kolla-ansible
bootstrap-servers is run, it fails like so:

The conditional check 'docker_storage_driver' failed. The error was: error
while evaluating conditional (docker_storage_driver): 'devicemapper' is
undefined

Ansible does not like evaluating strings as conditionals. This change switches
to using the length filter.

Both swift.conf and proxy-server.conf are affected be
/etc/kolla/config/swift/proxy-server.conf. However, some options in
proxy-server.conf are not valid in swift.conf.

This change keeps this path for proxy-server.conf, but modifies the path
for swift.conf to /etc/kolla/config/swift/proxy-server/swift.conf. The
same applies for other services, object-*, account-*, container-*.
