Subject: [PATCH] Extend example playbook to contain valid values

In case of standalone deployment of the role, it's important to avoid
client-installation on server-side, as this causes a race condition,
where deployed my.cnf is used before the respective user is created.

Patch also adds all requirements which needed for the role execution
in a standalone mode.
