use Fx to start and stop the host, swarm, autorelay and quicreuse (#2118)

* config: refactor AutoNAT construction into separate method

* config: use a lifecycle hook to start listening on swarm addresses

* use Fx to construct the host

* add a test for constructing a routed host

* use Fx hooks to start the host

* config: use Fx lifecycle hooks to start AutoRelay and for PeerRouting

* basichost: don't close the swarm

The swarm is not constructed by the basic host, thus is shouldn't be
closed by it.

* config: use Fx hook to close the quicreuse connection manager

* test for goroutine leaks when starting/stopping fx

To do this, I've had to move a few leaky tests into a separate package.
I've filed a bug for the AutoNAT issue (#2743) but the "error on
startup" issue is going to require some pretty invasive changes (we need
to construct _then_ start).

* go fmt

* Ignore one more top function

* Typo

* Ignore any not top
