------------------------------------

Attached .007 for Ankit – his latest from RB but rebased after my last change on the feature branch.

Has my +1, waiting to see what QA says.

> Spin-off of HBASE-20952.
> Ankit has started working on what he thinks a WAL API specifically for Replication should look like. In his own words:
> {quote}
> At a high level, it looks,
>  * Need to abstract WAL name under WalInfo instead of Paths
>  * Abstract the WalEntryStream for FileSystem and Streaming system.
>  * Build WalStorage APIs to abstract operation on Wal.
>  * Provide the implementation of all above through corresponding WalProvider
> {quote}
