Make kube2sky and skydns docker images cross-platform
ARM tracking issue: #17981
Continues on: #19216
Make it possible to create `kube2sky` and `skydns` docker images for ARM and other architectures too
Build in a container, so `golang` isn't a dependency
I've preserved the original default behaviour:
- `skydns`: It just compiles with go on host
- `kube2sky`: Build an image

Minor doc edits to development.md
Noted a few small clarity issues going through the development guide and while it mentioned local builds, it was missing instructions for building on a local go developer environment.

DONE:
1. refactor all predicates: predicates return fitOrNot(bool) and error(Error) in which the latter is of type
PredicateFailureError or InsufficientResourceError. (For violation of either MaxEBSVolumeCount or
MaxGCEPDVolumeCount, returns one same error type as ErrMaxVolumeCountExceeded)
2. GeneralPredicates() is a predicate function, which includes serveral other predicate functions (PodFitsResource,
PodFitsHost, PodFitsHostPort). It is registered as one of the predicates in DefaultAlgorithmProvider, and
is also called in canAdmitPod() in Kubelet and should be called by other components (like rescheduler, etc)
if necessary. See discussion in issue #12744
3. remove podNumber check from GeneralPredicates
4. HostName is now verified in Kubelet's canAdminPod(). add TestHostNameConflicts in kubelet_test.go
5. add getNodeAnyWay() method in Kubelet to get node information in standaloneMode
TODO:
1. determine which predicates should be included in GeneralPredicates()
2. separate GeneralPredicates() into:
a. GeneralPredicatesEvictPod() and
b. GeneralPredicatesNotEvictPod()
3. DaemonSet should use GeneralPredicates()

Allowing type object in kubectl swagger validation
Allowing `"type": "object"` in kubectl swagger validation.
We will cherrypick this in 1.2
This allows 1.2 kubectl to work with 1.3 api server which will use `"type":"object"` instead of `"type":"any"`.
