I find for most of the VPC tests we create a new VPC Offering which provides almost the same set of services as the "Default VPC Offering" already available by default. We also have a separate function to create this offering, enabling it and then create a VPC using this offering. I wonder why do we have to create vpc offerings for each test suite. Also, we don't expose create VPC offering in the UI. We do have an API for that, but I think we should just stick to the default ones available and then create network offerings as required for the test.
Except for one test suite - test_vpc_offerings.py, where we are actually testing vpc offerings, I don't think we should be creating vpc offerings elsewhere. Comments?
