[Casper] Wake On LAN

This would probably be more work on JAMFs part - but when I was testing 
out OCS Inventory NG, it had a great feature where it would use a client 
in a different subnet to issue commands that are limited by subnet.

For example:

JSS is in Subnet A
Client 1 is in Subnet B
Client 2 is in Subnet B

When Casper Remote could not SSH in the client 1 and couldnt do a 
Wake-on-lan because it was in subnet B -- Casper Remote would find a 
different client (2) in Subnet B that it could SSH into and have client 
2 do a Wake-on-lan to Client 1.

Obviously it would be some work on JSSs/Casper Remotes part to find 
Client 2, but it could probably base that on Network Segment and last 
check-in time.
