This object is used to indicate the threshold value in
percentage of free memory remaining in a memory pool.
If the free memory available goes below this threshold value and
if ciscoMemoryPoolLowMemoryNotifEnable is set to 'true',
ciscoMemoryPoolLowMemoryNotif will be generated. When the
available free memory comes back to the threshold value
ciscoMemoryPoolLowMemoryRecoveryNotif will be generated.
