bluechictl: status command to show nodes list

[mkemel]

Removing the bluechictl monitor node-connection functionality and move it to bluechictl status, slightly expanding it.

bluechictl status will print the list of nodes with their status and when it was last seen.

$ sudo bluechictl status
NODE                          | STATE     | LAST SEEN                   
=========================================================================
laptop                        | online    | now                                            
rpi4                          | offline   | never                       

bluechictl status node will print the same for for the node node

$ sudo bluechictl status laptop
NODE                          | STATE     | LAST SEEN                   
=========================================================================
laptop                        | online    | now                         

Also adding -w/--watch flag to bluechictl status command, allowing to continuously monitor the node/nodes status (like the original bluechictl monitor node-connection)

bluechictl status node unit retains the original functionality

Resolves #281

I think if you update the branch, the two failing integration tests will pass - these tests were recently added and a bit flaky. It has been improved in #699

LGTM

I'd like to have the -w option also for the unit, e.g.

bluechictl status laptop cow.service

But that can be done in a separate PR. I'll create an issue for it.

@engelmi thanks, I was exactly thinking about it while updating the docs
Pushed doc updates (with a small fix for the previous PR), in a new commit - please take a look. The commit is independent, no need to squash on PR merge
