Implement new server storage (#1016)

This is a new, custom implementation of the server storage based on a
"command-sourcing" log, which is required for the future replication
purposes. The existing streams/topic/partitions/segments storage remains
unchanged. This implementation removes the usage of Sled embedded DB and
comes with a built-in migration.
