Which Delta project/connector is this regarding?
Description
This PR is one of a series of PRs aiming to refactor the DML suites such that we can extend the existing suites to test with name-based table access.
Currently, all DML suites are centered around the
DeltaDMLTestUtilstrait that creates a test table stored intempPath. In this PR, all path-related elements in this trait will be abstracted out and put into a new specialized trait calledDeltaDMLByPathTestUtils.How was this patch tested?
