ovsdb: Add tests for transient ovsdb-server.

This variant of the ovsdb execution tests runs each transaction against a
separately started ovsdb-server.  The idea is that this should help to
ferret out any differences between what ovsdb-server has in memory and what
actually gets committed to disk.  There should not be any such differences,
but we need to test for that.
