Description

The recovery code needs to be reworked into the new WAL API

Might be tricky because we have the WALSplitter now which is not something that is "constant".

One thought was that we could support per-Region-WALs instead of per-RS-WALs with the Ratis-LogService WALs. We would need to figure out how to wrangle this inside of an implementation.
