How this pull request can be tested ?

Running the plugin in queries mode will add a total count output (and a corresponding queries.total.count metric) with the actual amount of requests, while the queries.total.persecond metric and Requests total output will contain the per-second values.

Before the fix:

# /usr/lib/centreon/plugins/centreon_mongodb.pl --plugin database::mongodb::plugin --hostname ... --username ... --password ... --mode=queries
OK: Requests total: 98 | 'queries.total.persecond'=98/s;;;0; 'queries.insert.persecond'=0.00/s;;;0; 'queries.insert.count'=0;;;0; 'queries.query.persecond'=96.35/s;;;0; 'queries.query.count'=1638;;;0; 'queries.update.persecond'=0.00/s;;;0; 'queries.update.count'=0;;;0; 'queries.delete.persecond'=0.00/s;;;0; 'queries.delete.count'=0;;;0; 'queries.getmore.persecond'=0.24/s;;;0; 'queries.getmore.count'=4;;;0; 'queries.command.persecond'=1.41/s;;;0; 'queries.command.count'=24;;;0;

After the fix:

# /usr/lib/centreon/plugins/centreon_mongodb.pl --plugin database::mongodb::plugin --hostname ... --username ... --password ... --mode=queries
OK: Requests total: 1.57/s, total count: 22 | 'queries.total.persecond'=1.57/s;;;0; 'queries.total.count'=22;;;0; 'queries.insert.persecond'=0.00/s;;;0; 'queries.insert.count'=0;;;0; 'queries.query.persecond'=0.00/s;;;0; 'queries.query.count'=0;;;0; 'queries.update.persecond'=0.00/s;;;0; 'queries.update.count'=0;;;0; 'queries.delete.persecond'=0.00/s;;;0; 'queries.delete.count'=0;;;0; 'queries.getmore.persecond'=0.14/s;;;0; 'queries.getmore.count'=2;;;0; 'queries.command.persecond'=1.43/s;;;0; 'queries.command.count'=20;;;0;
