Add `rm --all` and `rm --filter`

[fjying]

Add blackfish rm . to remove all the past services once This reduces the time to load all the past not used services when doing blackfish ls

I think the thing to do here is allow blackfish rm to accept filters with pattern matching as well as a convenience option --all.

The feature should allow actions such as:

blackfish rm --filter status=FAILED,image=text-*

which would delete all text-generation-inference services whose status is FAILED. The command to delete all services would be

blackfish rm --all

The --all option to remove all the services is great.

Alternatively, it could also accept

blackfish rm --status=FAILED --image=text-*
