[cli] add retrieval of zones

[andrei-toterman]

This PR adds the zones CLI command, for retrieving zones and their status.
It also adds AZ information to the list and info commands.
There is support for all the expected --format options.

There is also a change to the base Command class, in order to allow it to receive gRPC callbacks with const parameters.

@levkropp this can now be merged, right?

[levkropp]

@ricab still waiting for your review on #3926 then yes, everything except the GUI is all ready! 😄

I just got back to #3926, then I noticed this. Do you think in this case we should merge that one into this first? Normally we merge in sequence.
