Make various fixes to flex tests and fix some crashes
* Fixes two controller-manager crashes when a flex plugin gets removed from flex directory.
* Also enables e2e tests to run in local clusters and other environments.
* Removes disruptive from flex e2e tests because flex can be installed in a running cluster and does not require kubelet or controller-manager restart anymore.

Allow override of AllowCreateOnUpdate with new argument to Update
**What this PR does / why we need it**:
Changes the Update function signature to include a new bool which tells storage to override what the UpdateStrategy returns for AllowCreateOnUpdate. This is not exposed to the user, the handler is the one that sets this override value. Eventually the patch handler will set this to true, in order to provide more consistent apply behavior, without changing the existing PUT behavior.
Redo of https://github.com/kubernetes/kubernetes/pull/65075 but on master to reduce number of conflicts when we merge feature-serverside-apply with master.

GetCoreImage is a too generic function, that takes too many arguments. This
makes it prone to errors that may be difficult to trace. The solution is to
split it into the following couple of functions with a more targeted interface:
- GetKubeControlPlaneImage used to fetch Kubernetes control plane images or the
unified control plane image (if one is specified).
- GetEtcdImage is used to fetch the etcd image.
In addition to these, a couple of new utility functions are also created:
- GetKubeControlPlaneImageNoOverride used like GetKubeControlPlaneImage but
does not return the unified control plane image (even if it is set).
- GetGenericArchImage returns image path in the form of "prefix/image-goarch:tag"

Fixed the wrong elasticsearch node counter
**What this PR does / why we need it**:
I am experiencing the nasty bug during the deployment of the elasticsearch-logging statefulset on my custom Kubernetes in Azure (AzureDisk persistant storage). Let's imaging that we want two master nodes which our elasticsearch will try to find during the discovery procedure. Because of the delay between creation of two nodes (azure disk creation) there will be a situation when only one node exists in the service endpoint list and it will be enough to pass the elasticsearch logging discovery step. Only one node will be written to the elasticsearch.yml, but it expects two. Elasticsearch will not be able to find required two nodes. Then Kubernetes will terminate the first pod while the second pod is almost ready (remove that endpoint from service). Then it adds the ip of the second pod to the endpoint and discovery fails as well. This is the endless procedure.

Setup TLS with CA Cert for vsphere cloud provider
- Extend config to take a path to a CA Certificate
- Use the CA Cert when establishing a connection with the SOAP client
Testing
We provide certs and keys for tests as fixtures, `vclib/fixtures`.
Those were created (and can be regenerated) using `vclib/fixtures/createCerts.sh`.
At the moment it's possible to configure a CA path and at the same time allow insecure
communication between vsphere cloud provider and vcenter. This may
change in the future; we might opt for overwriting the insecure
communication if a CA is configured / log and transparently pass the
arguments to the vcenter command / other. To be discussed.
At the moment the CA is a global level configuration. In other
words, all vcenter servers need to use certificates signed by the same
CA. There might be use cases for different CA per vcenter server; to be
discussed.
**What this PR does / why we need it**:
This PR adds the option of configuring a trusted CA for the communication between the vsphere cloud provider and the vcenter control plane.
**Which issue(s) this PR fixes**:
Fixes#64222
**Special notes for your reviewer**:
**Release note**:
```release-note
- Can configure the vsphere cloud provider with a trusted Root-CA

Increase certain waiting time window in gpu_device_plugin e2e_node test.
Kubelet restart process seems to get a bit slower recently. From running
the gpu_device_plugin e2e_node test on GCE, I saw it took ~37 seconds
for kubelet to start CM DeviceManager after it restarts, and then took
~12 seconds for the gpu device plugin to re-register. As the result,
this e2e_node test fails because the current 10 sec waiting time is too
small. Restarting a container also seems to get slower that it sometimes
exceeds the current 2 min waiting time in ensurePodContainerRestart().
This change increase both waiting time to 5 min to leave enough space
on slower machines.
