    Avoid leaking security group quota reservations

    Fixes bug #1043765

    If you attempt to create a security group where one already exists using
    that name, a security groups quota reservation is leaked. Fix by
    ensuring the reservation is rolled back in all failure cases.

    Add a check to the tests to ensure that a reservation isn't leaked in
    any of our sad path tests for security group creation.
