Disconnect peers on timer ticks to unblock channel state machine

At times, we've noticed that channels with `lnd` counterparties do not
receive messages we expect to in a timely manner (or at all) after
sending them a `ChannelReestablish` upon reconnection, or a

HTLCs are committed and their expiration is met.

their node/reconnect to their peers, allowing them to start from a fresh
state such that the message we expect to receive hopefully gets sent. We

(regardless of whether they're a `lnd` node), which we opt to implement
here by awaiting their response within two timer ticks.

Never block a thread on the `PeerManager` event handling lock

If thre's a thread currently handling `PeerManager` events, the
next thread which attempts to handle events will block on the first
and then handle events after the first completes. (later threads
will return immediately to avoid blocking more than one thread).

This works fine as long as the user has a spare thread to leave
blocked, but if they don't (e.g. are running with a single-threaded
tokio runtime) this can lead to a full deadlock.

Instead, here, we never block waiting on another event processing
thread, returning immediately after signaling that the first thread
should start over once its complete to ensure all events are
handled.

While this could lead to starvation as we cause one thread to go
around and around and around again, the risk of that should be
relatively low as event handling should be pretty quick, and it's
certainly better than deadlocking.

Store + process pending `ChannelMonitorUpdate`s in `Channel`

`ChannelMonitorUpdate`s which are pending until we're ready to pass
them to users and have them be applied. However, if the

a `ChannelMonitorUpdate` we'll be confused on restart - seeing our
latest `ChannelMonitor` state as stale compared to our
`ChannelManager` - a critical error.

Luckily the solution is trivial, we simply need to store the
pending `ChannelMonitorUpdate` state and load it with the
`ChannelManager` data, allowing stale monitors on load as long as
