CiscoMap.py (proposed change)

[zenoss]

Following Paul's (pmorton) initial post at
http://community.zenoss.com/forums/viewtopic.php?p=12774#12774

...

Cisco has several OID's to get the s/n and the total mem from depending on the type of equipment.

On the other hand, twistedsnmp seems not to return any value at all when one of the OID's in the GetMap is not part of the tree.

To overcome that, I've used GetTableMap and came up with the following:

chet can you work this one though to inclusion please
