Rodolfo Alonso Hernandez 6615f248e2 [OVS][FW] Remote SG IDs left behind when a SG is removed
When any port in the OVS agent is using a security groups (SG) and
this SG is removed, is marked to be deleted. This deletion process
is done in [1].

The SG deletion process consists on removing any reference of this SG
from the firewall and the SG port map. The firewall removes this SG in
[2].

The information of a SG is stored in:
* ConjIPFlowManager.conj_id_map = ConjIdMap(). This class stores the
  conjunction IDS (conj_ids) in a dictionary using the following keys:

    ConjIdMap.id_map[(sg_id, remote_sg_id, direction, ethertype,
      conj_ids)] = conj_id_XXX

* ConjIPFlowManager.conj_ids is a nested dictionary, built in the
  following way:

    self.conj_ids[vlan_tag][(direction, ethertype)][remote_sg_id] = \
      set([conj_id_1, conj_id_2, ...])

This patch stores all conjuntion IDs generated and assigned to the
tuple (sg_id, remote_sg_id, direction, ethertype). When a SG is
removed, the deletion method will look for this SG in the new storage
variable created, ConjIdMap.id_map_group, and will mark all the
conjuntion IDs related to be removed. That will cleanup those rules
left in the OVS matching:
  action=conjunction(conj_id, 1/2)
