feat: uc image rm

[miekg]

Allow for image removal via the uc cmd line. This just does 'rm' not 'prune', but adds a missing option to uncloud to at least have the possibility to remove images remotely. SSH is of course still an option.

All the plumbing and docker rpcs is done. It needs an e2e test still.

See #167

this works:

% uc rm test-compose-predeploy
[+] Removing service test-compose-predeploy 2/2
 ✔ Container test-compose-predeploy/f36ca0aa6e85 on machine-1  Removed                            0.0s
 ✔ Container test-compose-predeploy/b71f8ed6c635 on machine-1  Removed                            10.1s

% uc image ls

Not sure if useful, but I also have an older draft branch (just updated it with main) that includes most, if not all, of the "missing" uc image ... commands like rm, prune, inspect, pull, and tag.

missed that, maybe that is a too big of an PR? (at least that would be my feeling as a maintainer). I might be worth doing prune and implementing the extra flags that are discussed in #167

[jabr]

Oh, yeah. I just meant it might be useful as a reference or to “strip for parts” if there is other functionality we want.

Breaking it into a few MRs is a good idea. I think prune and maybe inspect are the only ones that have come up for me that would have been convenient.
