[PATCH-next 05/11] lnst.Recipes.ENRT: add VirtualOvsBridgeVlanInGuestRecipe

From: Christos Sfakianakis <csfakian(a)redhat.com&gt;

Add ported recipe VirtualOvsBridgeVlanInGuestRecipe, implementing
old regression_tests/phase2/virtual_ovs_bridge_vlan_in_guest.xml.
Base it on previously ported SimplePerfRecipe.

v2: Rename devices that have "to_guest" label. Use 'tap' instead
of 'eth'.
