Enhancement: Topbeat ignore some filesystems

[samuraiii]

It would be nice to have a way to ignore some filesystems from topbeat reports (e.g. nfs mounts...)

I think this could be solved with the filtering in the future: #451

This should be easily done using the generic filtering feature where you can drop the event for certain filesystems.

If you wanted to be able to filter by filesystem type that would only be possible if Topbeat was enhanced to report the filesystem type (e.g. nfs, ext4).

[ruflin]

Closing this issue as generic filtering is now available for all beats.
