Fix scenario base functions
There were two issues introduced in [1] which are fixed here:
- Calling create_server() with parameter security_groups=None fails,
we need to use the "default" group instead of passing "None" to nova.
- The signature of create_secgroup_rules() was changed, we need to
append the new parameter at the end in order to preserve
compatibility with existing callers.
