We were specifying a region, but naming it as a zone in util.sh

The zone matters just as much as the region, e.g. for EBS volumes.

We also change the config to require a Zone, not a Region.
But we fallback to get the information from the metadata service.

Load docker images of kubernetes components after docker is installed.

Implement Balanced Resource Allocation (BRA) algorithm as a PriorityFunction in scheduler package.

Reorganized Request.DoRaw() to guarantee streams are closed

Improve validation and fix not throwing an error during ns delete

Use defer to cleanup allocated service ip in case of error

FieldSelector for node List()

Make DeepHashObject use SpewKeys

We're probably going to be doing a port allocation here also, so this needs some pre-simplifying.

Update spew to support better map key sorting.

Populate last terminated container information

Don't use command pipes for exec/port forward

Add return types to PUT, POST and PATCH methods.

Add command and argument control to changelog

Update to option enable client.QPS and client.Burst

and change default on max_requests_inflight.

integration: Randomize the order of the integration tests.

Added a test to verify 429 triggers a client retry based on
header. Forced resp.Body.Close() to close after each request,
which allows Golang to reuse the TCP connection to the server
(should reduce connection establishment under retries).
Possibly fixed a server leak of request bodies.

Also add return types for proxy and redirect handlers.

Balanced Resource Allocation policy can now be enabled to so that
host(s) with balanced resource usage would be preferred. The score
given by BRA also scales from 0 to 10 with 10 representing that the
resource usage is well balanced.
