   * consumer (for instance using an XId of 0), will
   * return such message. Similarly the pending message
   * will be listed by the XPENDING command, that
   * inspects the PEL.
   *
   * Once a consumer successfully processes a message,

   * most are mainly for internal use in order to transfer the
   * effects of XCLAIM or other commands to the AOF file and to
   * propagate the same effects to the slaves, and are unlikely to
   * be useful to normal users:
   *    IDLE <ms>: Set the idle time (last time it was delivered) of the message. If IDLE is not specified, an IDLE of 0 is assumed, that is, the time count is reset because the message has now a new owner trying to process it.
   *    TIME <ms-unix-time>: This is the same as IDLE but instead of a relative amount of milliseconds, it sets the idle time to a specific Unix time (in milliseconds). This is useful in order to rewrite the AOF file generating XCLAIM commands.
   *    RETRYCOUNT <count>: Set the retry counter to the specified value. This counter is incremented every time a message is delivered again. Normally XCLAIM does not alter this counter, which is just served to clients when the XPENDING command is called: this way clients can detect anomalies, like messages that are never processed for some reason after a big number of delivery attempts.
   *    FORCE: Creates the pending message entry in the PEL even if certain specified XIds are not already in the PEL assigned to a different client. However the message must be exist in the stream, otherwise the XIds of non existing messages are ignored.
   *    JUSTXID: Return just an array of XIds of messages successfully claimed, without returning the actual message. Using this option means the retry counter is not incremented.
