Some tests have constraints that were there only to help reduce runtime which
reduces coverage when running in exhaustive mode. The majority of the constraints
are because it adds no value to run the test across additional dimensions (or
it is invalid to run with those dimensions). Updates the tests that have
legitimate constraints to use two new helper methods for constraining the table format
dimension:
create_uncompressed_text_dimension()
create_parquet_dimension()
These will create a dimension that will produce a single test vector, either
uncompressed text or parquet respectively.

Remote fragments are waiting for the coordinator to pump rows but the coordinator
decided it was done. This caused remote fragments to hang. The coordinator was
in turn waiting for the remote fragments to finish.
