Fixed ignoring the rest of deployments after the first error in deployment controller & added logging of errors.

kubelet sends up status updates to flip the ready condition of a pod after the
pod is already in the running state. RunRC should wait until the pod condition
is ready to make sure there is no pending status update which may affect the
follow-up performance test.

Disable kubelet_perf test in GKE

In upstream the kubelet is responsible for all pods which have the spec.NodeName
set. In Mesos we have a two-stage scheduling process:

1. pods with a pre-set spec.NodeName are still scheduled by the scheduler.
2. The kubelet will only see them when a Mesos task was started and the executor
   passes the pod to the kubelet.

With this PR a pod with spec.NodeName which is gracefully terminated, but not
yet scheduled, e.g.

- because the termination happened just after creation and the scheduler was
  not fast enough
- because the NodeSelector does not match

is deleted by the Mesos scheduler.

We can assume that n != nil holds, because otherwise offers are skipped.

- pre-create node api objects from the scheduler when offers arrive
- decline offers until nodes a registered
- turn slave attributes as k8s.mesosphere.io/attribute-* labels
- update labels from executor Register/Reregister
- watch nodes in scheduler to make non-Mesos labels available for NodeSelector matching
- add unit tests for label predicate
- add e2e test to check that slave attributes really end up as node labels
