[Remote Store] Optimize remote store restore flow to not download all the files from remote if local disk already has data

Is your feature request related to a problem? Please describe.
A clear and concise description of what the problem is. Ex. I'm always frustrated when [...]

• When we trigger remote restore via RemoteStoreRecoverySource, we download all the segment files from remote irrespective of the fact that local disk may contain some of those files.
• We should provide a choice through RemoteStoreRestore flow whether all segment files should be downloaded from remote even if local disk already contains some of them

Describe the solution you'd like
Provide a parameter/setting to the user which allows them to control whether to download all segment files from remote during recovery of a remote backed shard

This is not relevant anymore as we only recover unassigned shards in remote restore.
