This PR adds test infrastructure for running tests with shared tables. This allows having hypertables with specific configurations usable for all tests. Since these tests also don't require creating a new database for each test case some of the overhead of the normal tests is removed. While this will lead to much faster query tests some tests will still require their own database to test things, but most queres could be moved to this infrastructure to improve test coverage and speed them up.
