* server: Immediately apply enable- and disable-peer to device
- fix#228
- the musl libc is used on Alpine, a minimal linux distribution commonly
used in docker images. It's also used on OpenWRT which might be of
interest to innernet.
Surprisingly, Restart=always may not _always_ restart the unit if it restarts too fast.
Set a combination of options which should make systemd truly restart innernet always.
See https://unix.stackexchange.com/q/289629/352972.
The `RestartSec=60` is the main and important one which would prevent systemd from ever failing
to restart innernet in the default settings (because with it it would never exceed the default
limit of 5 restarts in 10 seconds).
`StartLimitIntervalSec=0` option is a complementary one for explicitly disabling the logic, and
may be removed from this PR if deemed unnecessary.

added to `innernet {up,fetch,install}`:
--no-nat-traversal: Doesn't attempt NAT traversal
(prevents long time delays in execution of command)
--exclude-nat-candidates: Exclude a list of CIDRs from being
considered candidates
--no-nat-candidates: Don't report NAT candidates.
(shorthand for '--exclude-nat-candidates 0.0.0.0/0')
Closes#160
Before, only clients would report local addresses for NAT traversal. Servers should too! This will be helpful in common situations when the server is run inside the same LAN as other peers, and there's no NAT hairpinning enabled (or possible) on the router.
closes#146
