* Implement the Catalog V2 controller integration container tests
This now allows the container tests to import things from the root module. However for now we want to be very restrictive about which packages we allow importing.
* Add an upgrade test for the new catalog
Currently this should be dormant and not executed. However its put in place to detect breaking changes in the future and show an example of how to do an upgrade test with integration tests structured like catalog v2.
* Make testutil.Retry capable of performing cleanup operations
These cleanup operations are executed after each retry attempt.
* Move TestContext to taking an interface instead of a concrete testing.T
This allows this to be used on a retry.R or generally anything that meets the interface.
* Move to using TestContext instead of background contexts
Also this forces all test methods to implement the Cleanup method now instead of that being an optional interface.

On a few occasions I've had to read timeout stack traces for tests and
noticed that retry.Run runs the function in a goroutine. This makes
debuging a timeout more difficult because the gourinte of the retryable
function is disconnected from the stack of the actual test. It requires
searching through the entire stack trace to find the other goroutine.
By using panic instead of runtime.Goexit() we remove the need for a
separate goroutine.
Also a few other small improvements:
* add `R.Helper` so that an assertion function can be used with both
testing.T and retry.R.
* Pass t to `Retryer.NextOr`, and call `t.Helper` in a number of places
so that the line number reported by `t.Log` is the line in the test
where `retry.Run` was called, instead of some line in `retry.go` that
is not relevant to the failure.
* improve the implementation of `dedup` by removing the need to iterate
twice. Instad track the lines and skip any duplicate when writing to
the buffer.
