Jan Chaloupka 663fbce3a0 Kubelet: node allocatable resources: negative quantities should not be allowed 
When setting kube/system-resources for a node, negative quantities can result in
node's allocatable being higher then node's capacity.
Let's check the quantity and return error if it is negative.

Tim St. Clair e2ffd007f7 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.

Madhusudan.C.S 059c2aa799 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.
