Some of the environment variables have changed as devstack defaults
have changed. So look for the older env variables first and try the
newer ones later.
At a minimum you need the following for v3 authentication which is
the default with latest devstack. If you miss the Tenant information
then the token issued will be a unscoped token (and will not have any
service catalog information).

E2E test to verify clean up of stale dummy VM for vSphere dynamic provisioning
Verify if the dummy stale VM's created during dynamic provisioning are deleted by the clean up routine in vSphere cloud Provider.
**Testing Done:**
- Create a storage class with invalid policy on a VSAN datastore.
- Create a PVC using the above storage class
- Verify if the PVC is not bound.
- Delete the PVC.
- Sleep for 6 minutes so that vSphere Cloud Provider clean up routine can delete the stale dummy VM's.
- Verify if the VM is not present. Otherwise fail the test.

Add ping6 option for e2e ext connectivity test for IPv6-only clusters
e2e tests provide only an (IPv4) ping test for external connectivity.
We need a way to conditionally run a ping6 external connectivity check,
and disable the (IPv4) ping-based external connectivity check,
for end-to-end testing on IPv6-only clusters.
This feature will be needed for creating gating IPv6 CI tests.
fixes#53383
**What this PR does / why we need it**:
This adds an IPv6 (ping6) version of the external connectivity ping check to the e2e test suite,
and adds "Feature:" flags for selecting whether the IPv4 or IPv6 (or both) versions
of the connectivity test should be run. We need this change to be able to use the
e2e test suite in upstream gating IPv6 CI tests on IPv6-only clusters (at least until
dual-stack operation is fully supported in Kubernetes).

outputs `<none>` for colums not found
**What this PR does / why we need it**:
outputs `<none>` for columns specified by `-o custom-columns` but not found in object
currently kubectl outputs an error of "xxx is not found" when a column is not in the returned json (omitted because of empty value or no such field in the object type at all). This PR suppress this error but outputs `<none>` at that field. This makes it convenient to output the objects details, especially when getting objects of different type in one command.
example:
```
$ kubectl get deploy,rs,po -o custom-columns=NAMESPACE:.metadata.namespace,NAME:.metadata.name,REPLICAS:.status.replicas
NAMESPACE NAME REPLICAS
default deck 1
default deck-433074128 1

Use pointer for PSP allow escalation
Fixes#53437
The `AllowPrivilegeEscalation` field was added to PodSpec and PodSecurityPolicySpec in 1.8.0.
In order to remain compatible with pre-1.8.0 behavior, PodSecurityPolicy objects created against a previous release must not restrict this field, which means the field must default to true in PodSecurityPolicySpec. However, the field was added as a `bool`, not a `*bool`, which means that no defaulting is possible.
We have two options:
1. Require all pre-existing PodSecurityPolicy objects that intend to allow privileged permissions to update to set this new field to true
2. Change the field to a `*bool` and default it to true.
This PR does the latter. With this change, we have the following behavior:
A 1.8.1+ client/server now has three ways to serialize:
* `nil` values are dropped from serialization (because `omitempty`), which is interpreted correctly by other 1.8.1+ clients/servers, and is interpreted as false by 1.8.0
* `false` values are serialized and interpreted correctly by all clients/servers
* `true` values are serialized and interpreted correctly by all clients/servers
A 1.8.0 client/server has two ways to serialize:
* `false` values are dropped from serialization (because `omitempty`), which is interpreted as `false` by other 1.8.0 clients/servers, but as `nil` (and therefore defaulting to true) by 1.8.1+ clients/servers
* `true` values are serialized and interpreted correctly by all clients/servers
The primary concern is the 1.8.0 server dropping the `false` value from serialization, but I consider the compatibility break with pre-1.8 behavior to be more severe, especially if we can resolve the regression in an immediate point release.
```release-note
PodSecurityPolicy: Fixes a compatibility issue that caused policies that previously allowed privileged pods to start forbidding them, due to an incorrect default value for `allowPrivilegeEscalation`. PodSecurityPolicy objects defined using a 1.8.0 client or server that intended to set `allowPrivilegeEscalation` to `false` must be reapplied after upgrading to 1.8.1.

kubelet: add latency metrics to network plugin manager
This PR adds latency metrics to the network plugin operations, namely `GetPodNetworkStatus()`, `SetUpPod()`, and `TearDownPod()`.
I recently had to debug and issue where a PLEG relist hang was occurring due to a hang in a CNI plugin and it would have been really nice to have these. Between the these new metrics and `docker_operations_latency_microseconds`, we will be able to account for nearly all the time consuming routines in the PLEG relist.

Add check for IPv6 '::' when calculating kube-proxy's node IP
kube-proxy currently checks for a bind address of 0.0.0.0 (IPv4 all-zeros)
when calculating kube-proxy's node IP, but it does not check for
an address of '::' (IPv6 all-zeros). For either of those all-zeros
addresses, the node IP should be determined based on the hostname,
rather than using the address directly.
Also added a helpful log message when the kube-proxy protocol is
determined to be IPv6.
fixes#52613
**What this PR does / why we need it**:
This PR adds a check for a bind address of IPv6 '::' (all zeros) when kube-proxy is calculating its node IP,
similar to what is done for a bind address of IPv4 0.0.0.0. For either of these all-zeros addresses,
kube-proxy should derive the node IP based on the hostname, rather than use the bind address
directly.

Add required family flag for conntrack IPv6 operation
This change causes kube-proxy to supply the required "-f ipv6"
family flag whenever the conntrack utility is executed and the
associated service is using IPv6.
This change is required for IPv6-only operation.
Note that unit test coverage for the 2-line changes in
pkg/proxy/iptables/proxier.go and /pkg/proxy/ipvs/proxier.go will need
to be added after support for IPv6 service addresses is added to these
files. For pkg/proxy/iptables/proxier.go, this coverage will be added
either with PR #48551.
fixes#52027
**What this PR does / why we need it**:
Kube-proxy is currently not supplying the required "-f ipv6" family flag whenever it
calls the conntrack utility and the associated service is using an IPv6 service IP address.
This means that for IPv6-only operation, conntrack is not properly cleaning up
stale UDP connections, and this may be effecting ip6tables operation.
