[myloader] Add option to disable Galera Cluster (Wsrep) replication before importing

[joffrey92]

Hello,

by default myloader does set sql_log_bin = 0, which is useful.

When you use Galera Cluster (MySQL and Percona), setting sql_log_bin = 0 also disables wsrep replication.

When you use Galera Cluster (MariaDB), setting sql_log_bin = 0 doesn't disable wsrep replication. See: https://mariadb.com/kb/en/library/replication-and-binary-log-server-system-variables/#sql_log_bin

Could you please add an option in myloader, to support disabling (and/or enabling) wsrep replication ?

The command is:
set session wsrep_on = 0

Thanks in advance,
Joffrey
