Cluster: getKeysFromCommand() API cleaned up.

This API originated from the "diskstore" experiment, not for Redis
Cluster itself, so there were legacy/useless things trying to
differentiate between keys that are going to be overwritten and keys
that need to be fetched from disk (preloaded).

All useless with Cluster, so removed with the result of code
simplification.
