It's already possible to specify interfaces that should be scraped. This is required for routers that have a huge number of virtual interfaces, like BNGs.

devices:
  hostname.example.com:
    interfaces:
      - HundredGigE0/0/0
      - GigabitEthernet0

We should extend the feature to allow the use of regexes in the interface list.
Additionally we should allow to exclude specific interfaces based on a list of regexes.

The config interface would look like this:

devices:
  hostname.example.com:
    interfaces:
      - HundredGig.*
  hostname2.example.com:
    interfaces_excluded: 
      - Virtual-Template.*

To implement this we first need to fetch the list of all interfaces (show interface summary), filter based on our selectors and then fetch the individual interfaces.

When both interfaces and interfaces_excluded are empty we should continue to use the simple implementation where show interfaces is collected without further arguments, for performance reasons.
