Leo fd27570637 bridge: remove all supervisor.SignalHealthy calls 
Supervisor does not back off tasks that failed in a healthy state.

There are a couple places where we rely on supervisor for
application-level backoff, so we always want back-off. The distinction
is meant to enable runnables to implement their own specific back-off
logic, which we don't, so we can safely ignore it.

Fixes #37

Leo 8be34ac657 bridge: refactor processor logic into pkg/processor 
This increases modularity in preparation for integration testing
and addition of a CLI command hierarchy.

Leo 509d9c3d73 bridge: use mlockall(2) to prevent pages from being swapped out 
The extra capability is harmless and is, at worst, a DoS risk.

Leo 3b35ddc1ce bridge: propagate panics from runnables 
Any error that can be recovered by restarting a runnable
can also be recovered from by restarting the entire process.

If we encounter a panic, it's safer to restart the process than
attempting to limp along by restarting the runnable.

We always assume that an external process manager will restart
our process if it crashes. We already rely on this behavior for
libp2p errors which we handle by terminating the process, since libp2p
maintains global state that we can't clear.

Leo d6ef9c932c bridge: listen to eth lockups and aggregate signatures from all nodes 
Improved devnet setup to generate deterministic node and guardian keys.

Devnet setup routine that configures a dynamic guardian set on Ethereum.

Configurable number of nodes in Tiltfile.

Leo c4d53247d3 bridge: fix p2p routine restart 
Turns out, libp2p cannot be cleaned up so till this is fixed,
we have to exit if p2p dies.

Expose the root context to p2p and cancel it.
