Kolla environment currently uses haproxy
to fullfill HA in mariadb. This patch
is switching haproxy to proxysql if enabled.
This patch is also replacing mariadb's user
'haproxy' with user 'monitor'. This replacement
has two reasons:
- Use better name to "monitor" galera claster
as there are two services using this user
(HAProxy, ProxySQL)
- Set password for monitor user as it's
always better to use password then not use.
Previous haproxy user didn't use password
as it was historically not possible with
haproxy and mariadb-clustercheck wasn't
implemented.

Allow operators to set haproxy socket to admin level.
This is done via the flag haproxy_socket_level_admin which
is set to "no" by default.

For now role haproxy is maintaining haproxy
and keepalived. In follow-up changes there is also
proxysql added.
This patch is *only* renaming/moving stuff to more
prominent role loadbalancer, and moving also specific
templates to subdirectory.
This was done only to better diff in follow-up
changes.
