l2pop: Allow network types overridable

Browse Source 
Currently "tunnel_types" is used for two different purposes; l2pop and
check_segment_for_agent.  This commit introduces a new agent
configuration "l2pop_network_types" to allow overriding the former.

This will be used by ofagent, which wants l2pop info for TYPE_VLAN
as well.
