Determine if TF acceptance tests are racing and sweeping each other

[displague]

More interesting errors that seem unrelated. I wonder if the two versions of TF acceptance tests are running side-by-side and the sweeper from one test is knocking out the test resources of the other test. Most of these errors could be explained by a resource being deleted by an external actor.

If sweeping is the problem:

• and tests across PRs are racing, can we prevent that?
• and tests in the same PR are racing, can we prevent that?

Tests failures that may be evidence of sweeping:

I believe the reason for this test is one of the following:

• The testing account is not privileged to create BGP configs on projects
• The project is not ready when the POST /project/{id}/bgp-config request is sent

I tried to insert a 4-second delay between creating the project and posting to the bgp-config but that did not resolve the issue.

The 404s here will be resolved by $45.
The 403 will be resolved by #44 (although it is not clear to me at a glance why we attempted to convert a resource to layer-2 and then received a 403, perhaps because of sweeper racing).
