Prepare VolumeHost for running mount tools in containers
This is the first part of implementation of https://github.com/kubernetes/features/issues/278 - running mount utilities in containers.
It updates `VolumeHost` interface:
* `GetMounter()` now requires volume plugin name, as it is going to return different mounter to different volume plugings, because mount utilities for these plugins can be on different places.
* New `GetExec()` method that should volume plugins use to execute any utilities. This new `Exec` interface will execute them on proper place.
* `SafeFormatAndMount` is updated to the new `Exec` interface.
This is just a preparation, `GetExec` right now leads to simple `os.Exec` and mount utilities are executed on the same place as before. Also, the volume plugins will be updated in subsequent PRs (split into separate PRs, some plugins required lot of changes).

cni: print better error when a CNI .configlist is put into a .config
If the admin mistakenly puts a CNI configlist into a "conf" file, that's not correct, but kubelet will still read the config file and then fail to start the pod because "type=". Be a bit smarter about that. Should also be fixed in CNI, which I'm doing a PR for as well.

Updated gRPC vendoring to support Keep Alive
**What this PR does / why we need it**:
This PR bumps the version of the vendored version of gRPC from v1.0.4 to v1.5.1
This is needed as part of the Device Plugin API where we expect client and server to use the Keep alive feature in order to detect an error.
Unfortunately I had to also bump the version of `golang.org/x/text` and `golang.org/x/net`.

Add instance metadata from flag even when using image config.
Also add instance metadata from flag even when we are using image config.
* Sometimes we need to dynamically generate instance metadata, it's troublesome to put them into image config.
* Sometimes we want to apply instance metadata to all images, it's duplicated to add them to each image in the image config.

The "Saturate" phase of StatefulSet e2e tests verifies orderly startup
by controlling when each Pod is allowed to report Ready.
If a Pod unexepectedly goes down during the test, the replacement Pod
created by the controller will forget if it was already allowed to
report Ready.
After this change, the signal that allows each Pod to report Ready is
persisted in the Pod's PVC. Thus, the replacement Pod will remember that
it was already told to proceed to a Ready state.
This reverts commit f4afdecef8, reversing
changes made to e633a1604f.
This also fixes a bug where Kubemark was still using the core api scheme
to manipulate the Kubelet's types, which was the cause of the initial
revert.

This PR adds iSCSI initiatorname parameter to ISCSIVolumeSource
to enable automatic configuration of initiator name per volume.
This would allow for more fine grained configuration, and remove
the need to configure the initiator name on the host by
administrator.

MakeEventRecorder function cleanup
delete KubeletConfiguration arg since it is unused
fixes#50969
```release-note
NONE
```
During TestCreateWithNonExistentOwner, when creating a pod with a
non-existent owner, assume it's possible the pod will be deleted before
we start checking for the pod's existence. Assuming that the pod still
exists immediately after Create returns is flaky if the GC reacts very
quickly.
In 6c7245d464, code was added to
bail out if the directory that cadvisor monitored did not exist.
However, this breaks the earlier assumption that kubelet created
directories when needed in pkg/kubelet/kubelet.go's setupDataDirs()
method. setupDataDirs() happens much later, so basically kubelet
exits now.
So since cadvisor really needs this directory, let us just create
it

Default NODE_OS to gci on GCE installs
Looking at https://github.com/kubernetes/test-infra/tree/master/jobs,
any job with "cvm" in the name explicitly sets this variable, so I hope
it is only the default.
**Release note**:
```release-note
Change GCE installs (kube-up.sh) to use GCI/COS for node OS, by default.
