54257cbcca Rewrite JsonRPC requests using asyncio. 
- commands are async
 - the asyncio loop is started and stopped from the main script
 - the daemon's main loop runs in the main thread
 - use jsonrpcserver and jsonrpcclient instead of jsonrpclib

b1f606eaed lnchannel: start using "latest" and "next" instead of "current" and "pending" 
"current" used to be "oldest_unrevoked"; and pending was "oldest_unrevoked + 1"
but this was very confusing...
so now we have "oldest_unrevoked", "latest", and "next"
where "next" is "latest + 1"
"oldest_unrevoked" and "latest" are either the same or are offset by 1
(but caller should know which one they need)

rm "got_sig_for_next" - it was a redundant sanity check, that really
just complicated things

rm "local_commitment", "remote_commitment", "set_local_commitment",
"set_remote_commitment" - just use "get_latest_commitment" instead

f7c05f2602 Synchronize watchtower asynchronously: 
- remove remote_commitment_to_be_revoked
- pass old ctns to lnsweep.create_sweeptxs_for_watchtower
- store the ctn of sweeptxs in sweepStore database
- request the highest ctn from sweepstore using get_ctn
- send sweeptxs asynchronously in LNWallet.sync_with_watchtower
