Mike Spreitzer 7aa625fb37 Make timeout test properly liberal 
Make the test accept all the legitimate outcomes.

Expand the explanation of how TestPriorityAndFairnessWithPanicRecoveryAndTimeoutFilter/priority_level_concurrency_is_set_to_1,_queue_length_is_1,_first_request_should_time_out_and_second_(enqueued)_request_should_time_out_as_well is supposed to work.

Expand debug information that is available when the test fails.

Lukasz Szaszkiewicz 27a7c443bd cacher: with expiredBookmarkWatchers 
expiredBookmarkWatchers allows us to schedule the next bookmark event after dispatching not before as it was previously.
It opens a new functionality in which a watcher might decide to change when the next bookmark should be delivered based on some internal state.

Madhav Jivrajani 218ed2fae0 cacher: Use PodList type for use in GetList 
Using a Pod type in a GetList() call in a test
can panic at worst and error out at best. Here,
neither happened because the error condition
being tested for (cacher being stopped or not)
gets returned before the list pointer can be
enforced.

This commit changes the above to use PodList.

Tim Hockin 970b3ee9bb Initialize UID earlier in the Create process 
Before:
  Create()
      BeginCreate()
      BeforeCreate()
          init UID <---------------------
          strategy code

After:
  Create()
      init UID <-------------------------
      BeginCreate()
      BeforeCreate()
          strategy code

This also wipes UID early (suggested by David) and asserts it is set in
BeforeCreate().

Han Kang de98becc1d add explicit typing for continue tests 
Our tests are mostly error based and explicit error typing allows
us to test against error types directly. Having made this change also
makes it obvious that our test coverage was lacking in two branches,
specifically, we were previously not testing empty start keys nor were
we testing for invalid start RVs.
