Improve error reporting when flex driver has failed to initialize
**What this PR does / why we need it**:
This PR improves error reporting for the case when flex driver is failing to initialize. There are 2 improvements:
1) show only the plugin name instead of a full struct. This makes a message shorter and removes useless and internal information.

Allow setting service account with kubectl run
As more containers need to make use of the API, and more clusters are RBAC-enabled, which service account is used to run a particular container becomes more important.
This adds support to existing generators for setting the service account name in the pod spec.
```release-note
`kubectl run` learned how to set a service account name in the generated pod spec with the `--serviceaccount` flag.

Fix share name generation in azure file provisioner.
**What this PR does / why we need it**:
Azure file share name has a length limit of 63, but currently the code is using data volume's limit 75.
**Which issue this PR fixes**
With current implementation, when the cluster name is long, the resulting file share name could have a length of 75.
Also function `GenerateVolumeName` would produce double '-' when clusterName containing '-' is to be truncated.
In both cases, service would reject the creating file share request.
**Special notes for your reviewer**:
Please refer to:
https://docs.microsoft.com/en-us/rest/api/storageservices/naming-and-referencing-shares--directories--files--and-metadata#share-names
- Share names must be from 3 through 63 characters long.
- The name cannot contain two consecutive hyphens.

jsonpath filter: allow intermediate missing keys
**What this PR does / why we need it**:
In jsonpath, when filtering a list, if allowMissingKeys is true, skip
over any items that are missing an intermediate key in the filter,
instead of returning a confusing error.
For example, if the filter is
{.items[?(@.metadata.annotations.foo=="bar")].metadata.name}
we should return all items where metadata.annotations.foo == bar, but if
an item in the list does not have metadata, metadata.annotations, or
metadata.annotations.foo, skip it instead of erroring.

Support customized system spec in the node conformance test and create the GKE system spec
ref: https://github.com/kubernetes/kubernetes/issues/46891
- System specs are located in `test/e2e_node/system/specs`. Created one for validating GKE images in `test/e2e_node/system/specs/gke.yaml`.
- `--image-spec-name` can be used to specify a system spec in node e2e and conformance tests. This option maps to `SYSTEM_SPEC_NAME` in a test properties file, which is the user facing configuration. So, users can specify `SYSTEM_SPEC_NAME=gke` to run the image validation using the GKE system spec.
- If `SYSTEM_SPEC_NAME` is unspecified, the default spec (`system.DefaultSysSpec`) will be used.
- We can also use `make test-e2e-node SYSTEM_SPEC_NAME=gke` to run tests using GKE image spec.

Add quick-verify make rule.
This is useful for humans to run to catch obvious problems before
pushing commits and waiting for CI to run verify checks.
Quick mode only runs a whitelist of verify scripts that are reasonably fast.
I set the initial bar arbitrarily at <10s each on my workstation.
The whole set runs in <30s for me, assuming I had already run `make` and
`hack/godep-restore.sh`. This is compared to the full `make verify`
which takes [I don't know how long because I gave up after 45min].

azure: msi: add managed identity field, logic
**What this PR does / why we need it**: Enables managed service identity support for the Azure cloudprovider. "Managed Service Identity" allows us to ask the Azure Compute infra to provision an identity for the VM. Users can then retrieve the identity and assign it RBAC permissions to talk to Azure ARM APIs for the purpose of the cloudprovider needs.
Per the commit text:
```
The azure cloudprovider will now use the Managed Service Identity
to retrieve access tokens for the Azure ARM APIs, rather than
requiring hard-coded, user-specified credentials.

examples/volumes/flexvolume/nfs: check for jq and simplify quoting
**What this PR does / why we need it**:
This PR improves error reporting of the nfs flex plugin script. Before it output non-JSON error, when `jq` wasn't installed on the server:
```
$ /usr/libexec/kubernetes/kubelet-plugins/volume/exec/k8s~nfs/nfs getvolumename test
/usr/libexec/kubernetes/kubelet-plugins/volume/exec/k8s~nfs/nfs: line 87: jq: command not found
/usr/libexec/kubernetes/kubelet-plugins/volume/exec/k8s~nfs/nfs: line 88: jq: command not found
{"status": "Success", "volumeName": "/"}
```
K8s fails to unmarshal such output to show an error in the logs:
>E0606 19:32:30.196262 25700 driver-call.go:212] Failed to unmarshal output for command: getvolumename, output: "/usr/libexec/kubernetes/kubelet-plugins/volume/exec/k8s\~nfs/nfs: line 87: jq: command not found\n/usr/libexec/kubernetes/kubelet-plugins/volume/exec/k8s\~nfs/nfs: line 88: jq: command not found\n{\"status\": \"Success\", \"volumeName\": \"/\"}", error: invalid character '/' looking for beginning of value
After this change:

kubeadm: change the default bootstrap token TTL to 24 hours
**What this PR does / why we need it**:
This PR changes the TTL for the default bootstrap token generated by `kubeadm init` (without the `--token-ttl` parameter) and `kubeadm token create` (without the `--ttl` flag). Previously, the default TTL was infinite. After this change it is 24 hours.
~~The reasoning for 2 hours as a default is that it's 1) long enough that someone manually using kubeadm (copy-pasting) shouldn't have any issues and 2) short enough that if something is going to break, it should break while the user/admin is still paying attention to the cluster. I'm open to bikeshedding about the exact value, 2 hours is a bit of a strawman.~~
**Edit: updated this to 24 hours instead of 2 hours.**
This is a breaking change if you rely on infinite TTL tokens (e.g., if you had an ASG group of worker nodes). The old behavior is easily restored by passing `--token-ttl 0` to `kubeadm init` or the `--ttl 0` flag to `kubeadm token create`.
**Which issue this PR fixes**: fixes https://github.com/kubernetes/kubeadm/issues/343
**Special notes for your reviewer**:
This was discussed earlier today in SIG-cluster-lifecycle
**Release note**:
```release-note
Change the default kubeadm bootstrap token TTL from infinite to 24 hours. This is a breaking change. If you require the old behavior, use `kubeadm init --token-ttl 0` / `kubeadm token create --ttl 0`.

kubeadm: add a warning about the default token TTL changing in 1.8
**What this PR does / why we need it**:
This adds a warning to `kubeadm init` and `kubeadm token create` if they are run without the `--token-ttl` / `--ttl` flags. In 1.7 and before, the tokens generated by these commands defaulted to an infinite TTL (no expiration) in 1.8, they will generate a token with a 24 hour TTL.
The actual default change is in https://github.com/kubernetes/kubernetes/pull/48783. This change is separate so we can cherry pick the warning into the `release-1.7` branch.
**Which issue this PR fixes**: ref https://github.com/kubernetes/kubeadm/issues/343
**Special notes for your reviewer**:
This change is blocked on https://github.com/kubernetes/kubeadm/issues/343. These warnings should probably be removed in the 1.9 cycle.
**Release note**:
```release-note
Add a runtime warning about the kubeadm default token TTL changes in 1.8.
