Kubelet doesn't perform checkpointing and loses all its internal states after
restarts. It'd then mistaken pods from the api server as new pods and attempt
to go through the admission process. This may result in pods being rejected
even though they are running on the node (e.g., out of disk situation). This
change adds a condition to check whether the pod was seen before and categorize
such pods as updates. The change also removes freeze/unfreeze mechanism used to
work around such cases, since it is no longer needed and it stopped working
correctly ever since we switched to incremental updates.

Wait for rc store synced before syncing deployment

Improve error reporting a little in ingress e2e.

If not, using `go test -count=n` would make them pile up and ultimately
get to the limit of open files:

	client_test.go:522: expected an error, got Get http://127.0.0.1:46070/api: dial tcp 127.0.0.1:46070: socket: too many open files

Steps to reproduce (no longer fails):

	godep go test -short -run '^$' -o test .
	./test -test.run '^TestGetSwaggerSchema' -test.count 100

Note that this might not fail if your `ulimit -n` is not low enough.

Enforce minimum resource granularity of milli-{core, bytes} for Storage,
Memory, and CPU resource types. For Storage and Memory, milli-bytes are
allowed for backwards compatability, but the behavior is
undefinied (depends on docker implementation).

Keep options and flags distinct from initialization

Reduces the size of the app/server.go file and ensures that the flags
and their defaults are clearly separated.
