[vxlan tunnel]: Don't create encap mapper. Currently not supported (sonic-net#613)

* Pospone QueueMap initialization until activation of counters

* Generate queue maps only for front panel ports

* Currently we don't support vxlan tunnel encap mappers

* Adjust vxlan test. No encap mapper anymore.

* Add required underlay interface
