Keep track of data recovered from snapshots in RecoveryState (#76499) 
Adds new field to recovery API to keep track of amount of data
recovered from snapshots.

The normal recovered_bytes field remains and is also increased for
recovery from snapshot but can go backwards in the unlikely case
that recovery from snapshot fails to download a file.

Add peer recoveries using snapshot files when possible (#76237) 
This commit adds peer recoveries from snapshots. It allows establishing a replica by downloading file data from a snapshot rather than transferring the data from the primary. 

Enabling this feature is done on the repository definition. Repositories having the setting `use_for_peer_recovery=true` will be consulted to find a good snapshot when recovering a shard.
