Fix MariaDB bootstrap for 10.1 version

Option "wsrep_on" behaves differently between 10.0 and 10.1 [1]:
"Before MariaDB 10.1, even though this variable is ON by default,
its value get automatically adjusted based on whether mandatory
configurations to turn on Galera replication have been specified.
Since MariaDB 10.1, it is set to OFF by default and must be turned
on to enable Galera replication."

So on MariaDB 10.0 although wsrep_on set to OFF, its value will
automatically adjusted to ON because wsrep mandatory configurations
are set. Whereas on MariaDB 10.1, it will failed at galera provider
'wsrep_ready' checking because wsrep_on is set to OFF.

We can set wsrep_on to ON to handle both 10.0 and 10.1.

But, the point is that the cluster bits, which are creating a cluster
and wsrep_ready checking, are no need at bootstrap stage.

At bootstrap stage it mainly do two things:
Creating required system DBs (by mysql_install_db)
and securing the mariadb (by bootstrap_db).

After the bootstrap stage, it will create a cluster when starting the
first node.
