Upgrade Kubernetes libraries to v0.18.0
Add new lazy load KubernetesClientSet to avoid missing kubeconfig error
In kubernetes v1.18 kubeconfig validation was added. Minikube and Kind
both remove kubeconfig when stopping clusters. This causes and error
when running any helm commands because we initialize the client before
executing the command.

Don't delete a resource on upgrade if it is annotated with
helm.io/resource-policy=keep. This can cause data loss for users
if the annotation is ignored(e.g. for a PVC)

But instead use a newly initialized Scheme with only Kubernetes native
resources added. This ensures the 3-way-merge patch strategy is not
accidentally chosen for custom resources due to them being added
to the global Scheme by e.g. versioned clients while using Helm as a
package, and not a self-contained binary.

Fixes issue #7279.
Prevent the deletion of CRDs that were defined in the `templates/`
directory. This makes CRD deletion behaviour consistent with Helm
documentation:
> CRDs are never deleted. Deleting a CRD automatically deletes all of the
> CRD’s contents across all namespaces in the cluster. Consequently, Helm
> will not delete CRDs.
Previous the documentation only applied to CRDs that were defined in the
`crds/` directory. It did not consider that Charts could have CRDs in the
`templates/` directory (for example charts that were written before the
`crds/` directory feature or if the Chart author needed templated CRDs).

After doing some more digging, I found out that updating the status
of an `Ingress` object is completely optional. Because of this, Helm
cannot support ingresses with the `--wait` flag because there is no
standard way to identify that they are ready

* Drop dependency on k8s.io/kubernetes
https://github.com/helm/helm/issues/6606
Depending on k8s.io/kubernetes is not recommended by Kubernetes, and
forces dependencies of Helm to also depend on them. We are only using
this dependency in one relatively isolated occurance, which can be
easily copied over rather than depending on the entire Kubernetes.
Copying this code is not very desirable, so if we don't want to have
this duplication we can at least use this PR as a PoC and see if we can
get Kubernetes to publish the controller package as a separate Go module

Currently, if using the --atomic flag or deleting a release that failed due to an already existing
resource, Helm will deleting those resources that aren't managed by it. This PR fixes the issue
by checking for pre-existing resources during install and upgrade. This is done as a validation
step so the release will not even be started if resources currently exist. This PR is inspired by
@xchapter7x's work in #3477.
This also fixes a small bug in upgrade where deletes fail if the resource was already deletes

CRDs and other objects seen as unstructured cannot use strategic
merge patching. It has never been supported on CRDs. Previously,
cases like unstructured objects could have caused an unregistered
error. This is no longer the case.
This change explicitly looks for unstructured objects and handles
those using json merge patching.
Closes#3382
This error occures when resource is not found in helm release:
`Error: UPGRADE FAILED: no resource with the name "redis-cluster-sentinel" found`
Changed to:
`Error: UPGRADE FAILED: no ConfigMap with the name "redis-cluster-sentinel" found`
So now that resource can easily be found in cluster.
k8s client-go closes the ready channel that's passed in (see https://github.com/kubernetes/client-go/blob/master/tools/portforward/portforward.go#L171) This means that Tunnel's Close will always panic, as the client-go library will have closed then channel. This isn't reproducible unless helm.Client is externally, as the helm cli runner doesn't actually invoke Close.
Kind can change it's APIVersion with time, such as "Deployment" which was
"extensions/v1beta1" and then migrated to "apps/v1beta1" in Kube 1.6.
Name, Kind and optinally Namespace are used to find relevant Info
object for a original resource which is being upgraded, it safe enough,
as it is uniquely identifies an object.
This builds on previous work and adds more logging to follow
the full process of installing, updating, deleting, and rolling back.
This also standardizes capitalization of logs and small formatting
fixes
The current methodology generated its own RS slice instead of using
a helper method that uses a `clientset`. This caused some issues where
`FindNewReplicaSet` always returned `nil`. This switches the method and
removes some unneeded API calls and code.
Closes#2426
