Bug 1885: VM ingress rule is not installed for vlan networking

Related to Bug 1421 in openflowplugin where changes were made to how the vlan related match and actions are implemented. The current openflowplugin requires that the vlan match with present = false be added as a match before the mod_vlan_vid action will work. The patch adds the match condition.

There was an existing method to add the vlan vid and present flag. The method was enahanced to allow setting the present flag to true or false.
