feat: Set optional full-scan for deletion

[phil-park]

What this PR does / why we need it:

In this link (https://github.com/feast-dev/feast/pull/3857), I added function to perform a full-scan and delete data to save Redis memory. However, full-scan in Redis does not work beautifully, takes too long at production scale, and often fails in CI that performs feast-apply. So, I think it would be a good idea to add the 'full_scan_for_deletion' option in redis so that the user can select and delete it.

Which issue(s) this PR fixes:

I think this might be valuable in the interim, although you might want to chime in the discussion here as well #4133. The implicit consensus from there is to add a feast cleanup command that will delete all redundant keys from online store (keys that belong to deleted tables and also keys containing feature values that have expired according to ttl).
