Show only active Disk I/O (and network interface)

[dfadev]

Is your feature request related to a problem? Please describe.
DISK I/O section takes up too much space when you have 10+ disks and each are using device mapper.

Describe the solution you'd like
A toggle key that makes the DISK I/O section only show active disks where R/s or W/s is greater than zero.

Describe alternatives you've considered
None.

@dfadev As a workaround you can hide dm and sd disk from the Glances configuration file:

[diskio]
...
hide=loop.*,/dev/loop.*,dm.*,sd.*
...

[nicolargo]

Implemented in the develop branch by adding a hide_zero option.

To enable the feature:

[diskio]
...
hide_zero=True
...

[nicolargo]

@dfadev can you test the develop branch ?

Of course now that I see it I think hide_threshold_bytes also makes sense, so the tiny 14K writes don't show up.

Would be nice to have this on network interfaces too:

Also while I'm at it, a small delay before removing it from the list could make sense. Sort of debounce the removal so if activity drops for a few seconds then picks back up the entry doesn't phase in and out.

I see this was implemented for network interfaces too, very cool. Here's a quick video of it in action that shows why an entry removal delay and a configurable threshold could be nice.
