We are like 50% there to milestone 1. Next, implement shuffle logic,
python test client, and tx building/verification.
Who am I kidding.. we are still pretty far away. :)
- Util::RunInThread to run a lambda in a thread
- App exit handling cleanup
- EXMgr uses an id for clients now
- EXMgr keeps track of lagging clients
- EXMgr more aggressive with reconnects if no valid exclients
- Nits and refactorings and misc. cleanup
- Made the stale timeout be 2 mins now
- Check clients runs every 1 minute
- Added 'Controller' ABC which EXMgr is one of and the TcpServer will be
another.
