    Description

      At present if there are many agents available for the coordinator to send HSM work to, the coordinator will send as many actions as it can to the first agent before moving onto the next one.  This can result in pretty swamped singular agents while others remain idle.

      This feature adds a new tunable, max_hal_count, which governs how many hsm action list entries can be sent in a given request to an agent.  It also tracks when requests were sent to a specific agent last, enabling the coordinator to round robin over the pool of agents easily and better load-balance than it was able to do before.

      Patch to be sent shortly.
