TestTransportRemovesH2ConnsAfterIdle is experiencing flaky failures due to a bug in idle connection handling. Upon inspection, TestTransportRemovesH2ConnsAfterIdle is slow and (I think) not currently testing the condition that it was added to test. Using the new synctest package, this CL: - Adds a test for the failure causing flakes in this test. - Rewrites the existing test to use synctest to avoid sleeps. - Adds a new test that covers the condition the test was intended to examine. The new TestTransportIdleConnRacesRequest exercises the scenario where a never-used connection is closed by the idle-conn timer at the same time as a new request attempts to use it. In this race, the new request should either successfully use the old connection (superseding the idle timer) or should use a new connection; it should not use the closing connection and fail. TestTransportRemovesConnsAfterIdle verifies that a connection is reused before the idle timer expires, and not reused after. TestTransportRemovesConnsAfterBroken verifies that a connection is not reused after it encounters an error. This exercises the bug fixed in CL 196665, which introduced TestTransportRemovesH2ConnsAfterIdle.
