Reworked scenario tests to use their own non-default security groups

Moved _create_security_group_nova to base OfficialClientTest class, so
that now it can be used by all scenario tests. All scenario tests now
create security group with "loginable" rules explicitly and attach it to
servers instead of using "default" security group.
