[Not bug, but Enhancement]Rename Machine won't change the name's record in [nodes ls]

[1itt1eB0y]

I changed my kali(ID:2) to pi.
It says success and it was changed in my clients.
But it is still the old name in headscale's command output.

I noticed there is a given_name in DB, so why not make it list in the output of cli?

Observe same issue, it's pretty confusing, I'd suggest add a Hostname column in the nodes ls outputs.
And the mapping is:
machine.Name -> Hostname
machine.GivenName -> Name

I've implemented this enhancement, @kradalby if you think this is ok, I can open a PR
