7587: Refactor PySDK API tests to use TestCaseWithServers.

History: first this test case used entirely mock responses.  Then we
started running the API server to provide a discovery document.  Then
people added tests that expected to talk to a real test server,
particularly test_empty_list and test_nonempty_list.  These tests
would talk to the API server configured in the user's environment, and
fail if that's not a test API server.

Using TestCaseWithServers fixes the immediate bug in the tests, and
better reflects the current real state of the test case.

6358: Fix rendezvous probe order on Put.

Bug #1 was that KeepClient.put() was starting threads in the order
given by roots_map.iteritems(), instead of the order they were
supplied by weighted_service_roots(). This is fixed by using the same
logic get() was using.

Bug #2 was that ThreadLimiter didn't unblock threads in the same order
they were created by put(). This is fixed by adding a "set_sequence"
method to ThreadLimiter to indicate the order in which threads should
be unblocked.

The new test case confirms that put(copies=1) always makes requests in
the correct order.
