End to end build test

[charles-turner-1]

Is your feature request related to a problem? Please describe.

As described in #153 & #230, I think it would be wise to add an end to end test where we

1. Build a subset of the catalog, or an alternate test catalog.
2. Execute some queries against this subset/test catalog.

This is mostly a belt & braces approach in response to the intake take2 upgrade. Although we have good unit test coverage (~96-97%), end to end tests give us another layer of confidence that everything is behaving as we expect.

It's going to be necessary to only build a subset or a test catalog: building the full catalog takes on the order of 1.5 hours using 48 cores on Gadi, which is prohibitively expensive.

Describe the feature you'd like

End to end tests ensuring that catalog builds produce the expected outcomes.

Describe alternatives you've considered

• Not bothering with E2E tests
• Full catalog build, followed by some tests against the built catalog.
