There are going to be additional incremental nodes that wish to know if
vxlan mode is enabled. Instead of having to traverse the chassis in each
of those nodes, we can cache the vxlan status in the global config.
We can do the same with the max tunnel key based on the vxlan setting.

* v2 -> v3:
* Rebased, but no other changes made.
* v1 -> v2:
* Fixed compilation error.
* Fixed indentation of is_vxlan_mode declaration.
* Added Dumitru's ack.
