      Add new SFLUSH command to cluster for slot-based FLUSH (#13564) · d092d64d
      Moti Cohen authored
      This PR introduces a new `SFLUSH` command to cluster mode that allows
      partial flushing of nodes based on specified slot ranges. Current
      implementation is designed to flush all slots of a shard, but future
      extensions could allow for more granular flushing.
      
      **Command Usage:**
      `SFLUSH <start-slot> <end-slot> [<start-slot> <end-slot>]* [SYNC|ASYNC]`
      
      This command removes all data from the specified slots, either
      synchronously or asynchronously depending on the optional SYNC/ASYNC
      argument.
      
      **Functionality:**
      Current imp of `SFLUSH` command verifies that the provided slot ranges
      are valid and cover all of the node's slots before proceeding. If slots
      are partially or incorrectly specified, the command will fail and return
      an error, ensuring that all slots of a node must be fully covered for
      the flush to proceed.
      
      The function supports both synchronous (default) and asynchronous
      flushing. In addition, if possible, SFLUSH SYNC will be run as blocking
      ASYNC as an optimization.
