Description

Currently full / incremental backup is driven by BackupHandler (see call() method for flow).

This issue is to rewrite the flow using Procedure V2.

States (enum) for full / incremental backup would be introduced in Backup.proto which correspond to the steps performed in BackupHandler#call().
executeFromState() would pace the backup based on the current state.
serializeStateData() / deserializeStateData() would be used to persist state into procedure WAL.
