purge_relay_logs fails on MariaDB 10.0 about mha4mysql-node

[GeoffMontee]

The reason that this appears to be failing is because RaiseError is set to 1 in the DBI connection string here:

mha4mysql-node/bin/purge_relay_logs

Line 187 in ef26bde

{ PrintError => 0, RaiseError => 1 } );

If I change the connection string to this:

    my $dbh =
      DBI->connect( $dsn, $opt{user}, $opt{password},
      { PrintError => 1, RaiseError => 0 } );

Then it works:

[gmontee@slave ~]$ sudo ./purge_relay_logs --user=root --disable_relay_log_purge --relay_log_info=/var/lib/mysql/relay-log.info
