e4b369e1d7 storage: clean up timer in cacheWatcher.add 
In the e2e benchmarks, this timer is a significant source of garbage
and stale timers. Because the timer is not stopped after its use
in the select, it stays in the timer heap until it eventually fires
(5 seconds later). Under load, a lot of 5-second timers can pile up
before any start going away. The timer heap being large makes timer
operations take longer; the operations are O(log N) but N is still big.

The way to fix this in current versions of Go is to stop the underlying
timer explicitly, which this CL does for this one case.

There are many other places in the code that use the same idiom,
but those do not show up on profiles of the e2e server.
I am investigating changes for Go 1.7's runtime that would make
the old code behave like this new code transparently, so I don't
think it's worth updating any uses of the idiom that are not in
hot spots found with profiling.

Measuring 'LIST nodes' latency in milliseconds during e2e test
shows the benefit of this change.

Using Go 1.4.2:

BEFORE  p50: 148±7   p90: 328±19  p99: 513±29  n: 10
AFTER   p50: 151±8   p90: 339±19  p99: 479±20  n: 9

Using Go 1.6.0:

BEFORE  p50: 141±9   p90: 383±32  p99: 604±44  n: 11
AFTER   p50: 140±14  p90: 360±31  p99: 483±39  n: 10

3a56b68cc5 Add CI jobs to track the master and 1.2 branch with Trusty images 
Add two CI jobs that run e2e tests on GCE with Trusty images (on both the master
and the nodes) on the `master` and `release-1.2` branch. Both tests use the
latest Trusty build from its `HEAD`. We will use these jobs to guard
kubernetes-Trusty compatibility.

These jobs mimic the existing `kubernetes-e2e-gce` and `kubernetes-e2e-gce-1-2`,
which follow `kubernetes-build` and `kubernetes-build-1-2`, respectively.

Additionally, move all Trusty related jobs into one section in the config file.

deafa44d61 kubelet: send all recevied pods in one update 
The kubelet sync loop relies on getting one update as the signal that the
specific source is ready. This change ensures that we don't send multiple
updates (ADD, UPDATE) for the first batch of pods. This is required to prevent
the cleanup routine from killing pods prematurely.
