This change adds the ability for peers to report additional candidate endpoints for other peers to attempt connections with outside of the endpoint reported by the coordinating server.
While not a complete solution to the full spectrum of NAT traversal issues (TURN-esque proxying is still notably missing), it allows peers within the same NAT to connect to each other via their LAN addresses, which is a win nonetheless. In the future, more advanced candidate discovery could be used to punch through additional types of NAT cone types as well.

* Tidy code a bit thanks to clippy
Clippy 1.54 newly detects some redundant constructs, that's nice.
sort_unstable() should yield exact same results as sort() for `Vec<&str>`
and could be faster, clippy says.
* Add clippy to CI
The past behavior of clients was to, on every fetch from the server, update each of its peer's endpoints with the one reported from the server. While this wasn't a problem on certain types of NATs to help with holepunching, in some situations it caused previously working connections to no longer work (when one peer had a port-restricted or symmetric cone type NAT).
* wgctrl-rs(userspace): clean stale namefiles on starting up interface
Fixes#114
* wgctrl-rs(userspace): check connectability of interface socket in enumerate()
* Exit with code 1 (error) if wizard failed.
Should prevent error code 0 after
`creation failed: failed to create database (are you not running as root?).`
and similar errors.
* Switch error messages from stdin to stderr for init_wizard
This commit adds a subcommand to both the client and server to allow
changing the name of a peer. The peer retains all the same attributes as
before (public keys, IPs, admin/disabled status, etc.).
Closes#87
This subcommand takes a shell as an argument and generates shell
completions for that shell to stdout.
example:
```
$ innernet completions bash
OR
$ innernet-server completions bash
```
