RM8894

Adds a quota for the number of security groups allowed per port.
It was a silly hack because I was getting frustrated with this test. Long story short the test I copied was passing [1] and group back, as in a tuple of the list of ids and the actual group. I wanted to represent the over-quota bit but figured range(6) is equivalent to [1,2,3,4,5,6]

It's not strictly necessary, and I definitely concede it's not the easiest to read
