Simon Willnauer 5b07f81fcf Move reset recovery into RecoveriesCollection (#19466) ...

Today when we reset a recovery because of the source not being
ready or the shard is getting removed on the source (for whatever reason)
we wipe all temp files and reset the recovery without respecting any
reference counting or locking etc. all streams are closed and files are
wiped. Yet, this is problematic since we assert that some files are on disk
etc. when we finish writing a file. These assertions don't hold anymore if we
concurrently wipe the tmp files.

This change moves the logic out of RecoveryTarget into RecoveriesCollection which
basically clones the RecoveryTarget on reset instead which allows in-flight operations
to finish gracefully. This means we now have a single path for cleanups in RecoveryTarget
and can safely use assertions in the class since files won't be removed unless the recovery
is either canceled, failed or finished.

Closes  #19473
