Allow msg to set parameters for snmp nodes. (#299)
* I've modified the snmp libraries so that the server and the community can be defined by the msg. Error will be thrown if you try to override what was defined in the node. Verified that the contents of msg is no longer clobbered. Signed-off-by: Bryan Malyn <bimalyn@us.ibm.com> * Replaced tabs with 4 spaces. Signed-off-by: Bryan Malyn <bimalyn@us.ibm.com>
