Fix creation of prometheus user and grant permissions

Browse Source 
Prometheus is creating user and granting permissions
to database from which is gathering metrics. This
process is different when haproxy/proxysql is used.

Proxysql:

  - kolla-ansible should use root_shard_ID user to connect
    to ProxySQL endpoint and it is routed to proper shard.

Haproxy:

  - kolla-ansible should use root user to connect to HAProxy
    endpoint and that's all.

If proxysql is not used, mariadb role will not create user
shard_root_ID user in bootstrap (from my perspective of view
it should), and therefore it will fail when HAProxy is used.

This patch is just fixing user to connect.
