Allow BasicEndToEndTest to run multiple times locally (#7069)
Allow BasicEndToEndTest to run multiple times locally (#7069)

The topics used in a bunch of the cases in BasicEndToEndTest had no
unique identifier, so if you ran it multiple times against the same
standalone cluster, they would fail, as the topics would already have
some state.

This change adds the unique identifer to the topics.
