      Description

      I think we need to provide a way to opt out of response trackers for DVS, and I was thinking it would be useful, at least for testing purposes, to have a parameter to control the behavior of response tracking. I was thinking:
      1. Create a parameter that allows them to be enabled:
      1.1 For all messages (default)
      1.2 Only PUTs
      1.3 Only GETs
      1.4 Internal LNet traffic only (discovery messages and pings)

      i.e. we can't turn it off for discovery messages and pings but we could for all other messages.
      To support 1.4 we could have a new MD option that says "attach an rspt regardless of the param".
      Then we could have another MD option that says "do not attach an rspt regardless of the param". We could use that for DVS.
