This patch adds basic ratelimiting to sending out AckPackets
and non AckPackets. This provides a basic way to prevent
aprsd from sending out packets as fast as possible, which isn't
great for a bandwidth limited network.
This patch also adds some keepalive checks to all threads in the
threadslist as well as the network client objects (apris, kiss)
This patch moves the plugin manager to early in the startup
process so that the plugins get loaded, which also means each
plugin's custom config settings will be in the CONF object.
This allows dumping the entire CONF with all the plugin settings.
This patch introduces rpyc based RPC client/server for
the flask web interface to call into the running aprsd server
command to fetch stats, logs, etc to send to the browser.
This allows running the web interface via gunicorn command
gunicorn -k gevent --reload --threads 10 -w 1 aprsd.flask:app --log-level DEBUG
