[systest] Perform 'firewall test' for various network configurations

[Artem Panchenko]

In our system tests we have a check for firewall on slaves :

https://github.com/stackforge/fuel-main/blob/master/fuelweb_test/helpers/security.py#L85

which is currently performed only in non-HA test "deploy neurton gre":

https://github.com/stackforge/fuel-main/blob/master/fuelweb_test/tests/test_neutron.py#L78

That is not optimal place for that check, because "deploy_neutron_gre" test group is used in many important CI jobs, e.g. bvt, fueillib_review, etc. which are built very often, because firewall check rarely returns false-positive alert: https://bugs.launchpad.net/fuel/+bug/1378745 (most probably due to virtualization/performance issues) and introduces additional delays.

Also, we should perform this check in other tests which have different environment configurations (HA, NeutronVlan, NovaNetwork).

    Check firewall on various cluster configurations

    For different environment configurations (simple/HA,
    NovaNetwork/Neutron) different puppet manifests and
    deployment scenarios can be used, so firewall config
    can also be varied. Firewall configuration could be
    distorted after HA failover, node addition or cluster
    restart. That's why it is necessary to perform
    firewall check in few system tests.
