Check Centreon Map Session event queue size

Example:

perl centreon_plugins.pl --plugin=apps::centreon::map::jmx::plugin --custommode=jolokia --url=http://10.30.2.22:8080/jolokia-war --mode=event-queue

=over 8

=item B<--warning>

Set this threshold if you want a warning if global sessions event queue size match threshold 

=item B<--critical>

Set this threshold if you want a warning if global sessions event queue size match threshold
