8649628c6c Make POD container last OOM victim. 
Setting the oom_score_adj of the PID of the POD container to -100 which is less
than the default of 0. This ensures that this PID is the last OOM victim
chosen by the kernel.

Fixes #3067.

Don't delete the pod infrastructure container on health check failures.

5d6ad845cc Use Docker name (not ID) to parse Kubernetes components. 
Since the parsing function doesn't return an error all the components
returned empty strings. This caused us to enforce the MaxContainerLimit
as a global limit instead of a per-container limit.

Fixes #4413.

e8c33b7916 Add timeouts to HealthChecks and retry checks 
Fixes issue #3532. Added timeouts for HTTP and TCP checks
and enabled kubelet/probe to kubelet#maxRetries times
before declaring Failure.

Added Probe.TimeoutSecs to API

Probe variants now check container.LivenessProbe.TimeoutSeconds
Also added a test for timeouts in http_test.go.

5e36f63f8b Adding ResourceRequirementSpec to v1beta1, v1beta2, and v1beta3 APIs. The old resource 
quantities 'CPU' and 'Memory' will be preserved until support for v1beta1 and v1beta2 APIs are
dropped.
Improved resource validation in the process.
