Find module searches paths on managed server. Since role path and custom
Kolla config is located on deployment node and deployment node is not
considered to be a managed server, Monasca plugin files cannot be found.
After the deployment container running Monasca agent collector stucks in
restart mode due to missing plugin files.

The problem does not occur if deployment was started from a managed
server (eg. OSC). The problem occurs if the deployment was started from
a separate deployment server - a common case.

This change enforces running find module locally on deployment node.

In multinode deployments creating default Grafana organization failed,
because Ansible attempted to call Grafana API in the context of each
host in the inventory. After creating organization via the first host,
subsequent attempts via the remaining hosts failed due to already
existing organization. This change enforces creating default
organization only once.

Other tasks using Grafana API have been enforced to be ran only once as
well.

when using ceilometer+gnocchi, for every notification sample, ceilometer
will update the resource even if is not updated.

We should add [cache] section to make ceilometer cache the resource, and
stop send the useless update request.

blueprint database-backup-recovery

Introduce a new option, mariadb_backup, which takes a backup of all
databases hosted in MariaDB.

Backups are performed using XtraBackup, the output of which is saved to
a dedicated Docker volume on the target host (which defaults to the
first node in the MariaDB cluster).

It supports either full (the default) or incremental backups.
