Done. Here are 2 patches for master and RHEL6 branches for
fence_apc_snmp agent, with added Tripplite PDU support.

I've tested the patch for RHEL6 branch with my Tripplite PDU. And as you
could have noticed, there is no difference between the patch for RHEL6
and one for master branch, thus, you can assume tests is OK for master
as well...

As you can see from fence_apc_snmp's original README, it doesn't support
ganged or 'daisy-chained' switches yet, thus nothing was changed here.
