Pod deletion observation is flaking, increase timeout and debug more
We can afford to wait longer than 30 seconds, and we should be printing
more error and output information about the cause of the failure.

Add storage.k8s.io/v1 API
v1 API is direct copy of v1beta1 API. This v1 API gets installed and exposed in this PR, I tested that kubectl can create both v1beta1 and v1 StorageClass.
~~Rest of Kubernetes (controllers, examples,. tests, ...) still use v1beta1 API, I will update it when this PR gets merged as these changes would get lost among generated code.~~ Most parts use v1 API now, it would not compile / run tests without it.
**Release note**:
```
Kubernetes API storage.k8s.io for storage objects is now fully supported and is available as storage.k8s.io/v1. Beta version of the API storage.k8s.io/v1beta1 is still available in this release, however it will be removed in a future Kubernetes release.
Together with the API endpoint, StorageClass annotation "storageclass.beta.kubernetes.io/is-default-class" is deprecated and "storageclass.kubernetes.io/is-default-class" should be used instead to mark a default storage class. The beta annotation is still working in this release, however it won't be supported in the next one.

Supports 'ensure exist' class addon in Addon-manager
Fixes#39561, fixes#37047 and fixes#36411. Depends on #40057.
This PR splits cluster addons into two categories:
- Reconcile: Addons that need to be reconciled (`kube-dns` for instance).
- EnsureExists: Addons that need to be exist but changeable (`default-storage-class`).
The behavior for the 'EnsureExists' class addon would be:
- Create it if not exist.
- Users could do any modification they want, addon-manager will not reconcile it.
- If it is deleted, addon-manager will recreate it with the given template.
- It will not be updated/clobbered during upgrade.
As Brian pointed out in [#37048/comment](https://github.com/kubernetes/kubernetes/issues/37048#issuecomment-272510835), this may not be the best solution for addon-manager. Though #39561 needs to be fixed in 1.6 and we might not have enough bandwidth to do a big surgery.

Switch scheduler to use generated listers/informers
Where possible, switch the scheduler to use generated listers and
informers. There are still some places where it probably makes more
sense to use one-off reflectors/informers (listing/watching just a
single node, listing/watching scheduled & unscheduled pods using a field
selector).
I think this can wait until master is open for 1.7 pulls, given that we're close to the 1.6 freeze.
After this and #41482 go in, the only code left that references legacylisters will be federation, and 1 bit in a stateful set unit test (which I'll clean up in a follow-up).
@resouer I imagine this will conflict with your equivalence class work, so one of us will be doing some rebasing 😄

This PR is to modify the containerized mounter script to use chroot
instead of rkt fly. This will avoid the problem of possible large number
of mounts caused by rkt containers if they are not cleaned up.
Fix bash command's execution in MakePod().
Add isPriviledged as a parameter to MakePod().
Move PD utils to pv_util.go
Ran all the tests in pd.go, persistent_volumes.go,
persistent_volumes-disruptive.go.
These changes are needed for the PV upgrade test I am working on.

Switch admission to use shared informers

node cache don't need to get all the information about every
candidate node. For huge clusters, sending full node information
of all nodes in the cluster on the wire every time a pod is scheduled
is expensive. If the scheduler is capable of caching node information
along with its capabilities, sending node name alone is sufficient.
These changes provide that optimization in a backward compatible way
- removed the inadvertent signature change of Prioritize() function
- added defensive checks as suggested
- added annotation specific test case
- updated the comments in the scheduler types
- got rid of apiVersion thats unused
- using *v1.NodeList as suggested
- backing out pod annotation update related changes made in the
1st commit
- Adjusted the comments in types.go and v1/types.go as suggested
in the code review
Where possible, switch the scheduler to use generated listers and
informers. There are still some places where it probably makes more
sense to use one-off reflectors/informers (listing/watching just a
single node, listing/watching scheduled & unscheduled pods using a field
selector).

Bump golang versions to 1.7.5
**What this PR does / why we need it**: While #41636 might not make it in until 1.7, this would bump current golang versions from 1.7.4 to 1.7.5 to integrate the fixes from that patch version. This would include, among other things, a fix to ensure cross-built binaries for darwin don't have certificate validation errors (golang/go#18688)

Switch statefulset controller to shared informers
Originally part of #40097
I *think* the controller currently makes a deep copy of a StatefulSet before it mutates it, but I'm not 100% sure. For those who are most familiar with this code, could you please confirm?
