[Nagstamon 3.10.1] add filter by poller

[ASLLR]

Hi everyone, that is not really an issue but a feature request.

i would like to know if we can more filter on nagstamon, like we can filtering on centreon interface. In my case, i would like to filter on a specific poller or hostgroup to see only my hosts and not the others. That's can be possible ?

Thank you in advance,

Best regards,
