9bc2b43064 Set the podAttachAndMountTimeout to a lower value
If the mount operation exceeds the timeout, it will return an error and the
pod worker will retry in the next sync (10s or less). Compared with the
original value (i.e., 10 minutes), this frees the pod worker sooner to process
pod updates, if there are any.

Automatic merge from submit-queue

Fixes and improvements to Photon Controller backend for kube-up

- Improve reliability of network address detection by using MAC
  address. VMware has a MAC OUI that reliably distinguishes the VM's
  NICs from the other NICs (like the CBR). This doesn't rely on the
  unreliable reporting of the portgroup.
- Persist route changes. We configure routes on the master and nodes,
  but previously we didn't persist them so they didn't last across
  reboots. This persists them in /etc/network/interfaces
- Fix regression that didn't configure auth for kube-apiserver with
  Photon Controller.
- Reliably run apt-get update: Not doing this can cause apt to fail.
- Remove unused nginx config in salt

Kubelet Volume Attach/Detach/Mount/Unmount Redesign

This PR redesigns the Volume Attach/Detach/Mount/Unmount in Kubelet as proposed in https://github.com/kubernetes/kubernetes/issues/21931

```release-note
A new volume manager was introduced in kubelet that synchronizes volume mount/unmount (and attach/detach, if attach/detach controller is not enabled).

This eliminates the race conditions between the pod creation loop and the orphaned volumes loops. It also removes the unmount/detach from the `syncPod()` path so volume clean up never blocks the `syncPod` loop.
