If mountPath is missing, prefix with root dir.
If `mountPath` is not absolute, add the os-specific root directory as a prefix.

Note to @thockin I left the validation in place, in seems like it is a net win, since it will give a decent
error message to most people, but the fall-back defaulting is there if it doesn't catch 'c:'
I'm happy to rip out the validation if that is preferable to everyone. Let me know.
```release-note
If a non-absolute mountPath is passed to the kubelet, prefix it with the appropriate root path.

TolerationToleratesTaint was incorrect: if the toleration.Key is empty and
taint is non-empty, it should not return false. It was also not used anywhere.
The correct implementations are in staging/src/k8s.io/api/core/v1/toleration.go
and pkg/apis/core/v1/helper/helpers.go

add back defaulting for parameter decoding
At the beginning of 1.7, we removed the last "conversion causes defaulting". This broke the "default to true" behavior for exec and attach options, but we didn't notice. This removes the broken defaulter (you can default a non-point bool to true on an object) and adds back defaulting to parameter codecs.

Make sure that storage request of pvc is not zero
I do not know whether we should add the checking zero logic to `ValidateResourceQuantityValue`.
But at lease we should do this when validate PVC. If PVC requests 0Gi storage,it does not make sense to provision that volume.
Volume plugins will not check whether the request of PVC is 0 when they run `CreateVolume` or `CreateImage` called by `Provision()`
