Postgres support

[dzdidi]

Running LSP node means to maintain few big routing channels with big nodes, sometimes in a b2b relationship and many small private channels with customers.
It is necessary to have a continuous replication of the channel state database. Currently implemented sqlite does not have replication capabilities.
There is no need to have dockerization or anything else. Just allow server to connect to postgresql instance (remote?) which will handle replication, backup etc with it own settings and configuration

Yes, this is planned,
mentioned in #12 as bonus item.
Currently planned after alpha.
