Connext backup & restore

[kilrau]

xud-backup daemon should back up the connext folder the same way it does currently with the xud & lnd scb backup files + make sure it works with xud-docker

For LND, backup happens by calling subscribeChannelBackups from LND side, but I couldn't see such a backup endpoint for connext? Could you please be more specific? @kilrau

Hmm yeah needs connext/rest-api-client#99 I guess. What we can do for now, is simply copy the connext folder in certain intervals. Thoughts? @sangaman @erkarl

FYI, with Indra the channel state can also be restored from the node. Not ideal, but we might not want to invest time in V1 related activities since we're upgrading to V2 soon.

Agreed, lets hold off on this one @rsercano
