kubelet: move most of kubelet server configuration to a config object.
...
This is part of migrating kubelet configuration to the componentconfig api
group and is preliminary to retrofitting client configuration and
implementing full fledged API group mechinary.

Implement node Allocatable
...
Add `kube-reserved` and `system-reserved` flags for configuration
reserved resources for usage outside of kubernetes pods. Allocatable is
provided by the Kubelet according to the formula:
```
Allocatable = Capacity - KubeReserved - SystemReserved
```
Also provides a method for estimating a reasonable default for
`KubeReserved`, but the current implementation probably is low and needs
more tuning.

Mitigate node out of disk status oscillation by delaying it.
...
Implement a flag that defines the frequency at which a node's out of
disk condition can change its status. Use this flag to suspend out of
disk status changes in the time period specified by the flag, after
the status is changed once.
Set the flag to 0 in e2e tests so that we can predictably test out of
disk node condition.
Also, use util.Clock interface for all time related functionality in
the kubelet. Calling time functions in unversioned package or time
package such as unversioned.Now() or time.Now() makes it really hard
to test such code. It also makes the tests flaky and sometimes
unnecessarily slow due to time.Sleep() calls used to simulate the
time elapsed. So use util.Clock interface instead which can be faked
in the tests.

Refactor kubelet server into its own package
...
Refactor Kubelet's server functionality into a server package. Most
notably, move pkg/kubelet/server.go into
pkg/kubelet/server/server.go. This will lead to better separation of
concerns and a more readable code hierarchy.

Set resyncInterval to one minute now that we rely on the generic pleg to trigger

workers need to wake up sooner to retry. Set the sync error backoff period to
10 second in this case.

Default to hardcodes for components that had them, and 5.0 qps, 10 burst

Unclear if maybe it'd be better to just assume these are set as part of
the incoming kubeconfig. For now just exposing them as flags since it's
easier for me to manually tweak.
