Print osImage and kubeletVersion for nodes before and after GCE upgrade
This will print, e.g.:
```
== Pre-Upgrade Node OS and Kubelet Versions ==
name: "e2e-test-mtaufen-master", osImage: "Google Container-VM Image", kubeletVersion: "v1.4.5-beta.0.45+90d209221ec8dc-dirty"
name: "e2e-test-mtaufen-minion-group-jo79", osImage: "Debian GNU/Linux 7 (wheezy)", kubeletVersion: "v1.4.5-beta.0.45+90d209221ec8dc-dirty"
name: "e2e-test-mtaufen-minion-group-ox5l", osImage: "Debian GNU/Linux 7 (wheezy)", kubeletVersion: "v1.4.5-beta.0.45+90d209221ec8dc-dirty"
name: "e2e-test-mtaufen-minion-group-qvbq", osImage: "Debian GNU/Linux 7 (wheezy)", kubeletVersion: "v1.4.5-beta.0.45+90d209221ec8dc-dirty"
```
Let me know what output format you prefer and I'll see if I can make it work, I have the extent of flexibility allowed by jsonpath.

kubelet bootstrap: start hostNetwork pods before we have PodCIDR
Network readiness was checked in the pod admission phase, but pods that
fail admission are not retried. Move the check to the pod start phase.

It seems like the `kubectl` behavior was introduced in #29236: if `current-context` is set to something invalid, it now complains.

[Kubelet] Use the custom mounter script for Nfs and Glusterfs only
This patch reduces the scope for the containerized mounter to NFS and GlusterFS on GCE + GCI clusters
This patch also enabled the containerized mounter on GCI nodes
Shepherding multiple PRs through the submit queue is painful. Hence I combined them into this PR. Please review each commit individually.
