[PATCH-next 07/11] lnst.Recipes.ENRT: add VirtualOvsBridgeVlanInGuestMirroredRecipe

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

Add ported recipe VirtualOvsBridgeVlanInGuestMirroredRecipe,
implementing old regression_tests/phase2/virtual_ovs_bridge_vlan
_in_guest_mirrored.xml. Base it on previously ported SimplePerfRecipe.

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