uss: disable memory accounting for the snapshot daemon

* Bring in option to disable memory accounting for a glusterfs process
  This reverses the changes done by the commit
  7fba3a88f1ced610eca0c23516a1e720d75160cd.

* Change the key from "memory-accounting" to "no-memory-accounting", as by
  default all the glusterfs process enable memory accounting now. So to
  disable memory accounting for some process, "no-mem-accounting" argument has
  to be passed.
