[PATCH-next 2/7] lnst.Recipes.ENRT: add VlansRecipe

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

Add ported recipe VlansRecipe, implementing old
regression_tests/phase1/3_vlans.xml. Its structure is based
on previously ported SimplePerfRecipe. Due to limitations in the
current EnrtConfiguration class, a single vlan test pair is chosen.

v2: Keep 2 vlans.
