If two `helm upgrade`s are executed at the exact same time, then one of
the invocations will fail with "already exists".
If one `helm upgrade` is executed and a second one is started while the
first is in `pending-upgrade`, then the second invocation will create a
new release. Effectively, two helm invocations will simultaneously
change the state of Kubernetes resources -- which is scary -- then two
releases will be in `deployed` state -- which can cause other issues.
This commit fixes the corrupted storage problem, by introducting a poor
person's lock. If the last release is in a pending state, then helm will
abort. If the last release is in a pending state, due to a previously
killed helm, then the user is expected to do `helm rollback`.

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.

The memory driver is used for go tests. It can also be used from the
command-line by setting the environment variable HELM_DRIVER=memory.
In the latter case however, there was no way to pre-provision some
releases.
This commit introduces the HELM_MEMORY_DRIVER_DATA variable which
can be used to provide a colon-separated list of yaml files specifying
releases to provision automatically.
For example:
HELM_DRIVER=memory \
HELM_MEMORY_DRIVER_DATA=./testdata/releases.yaml \
helm list --all-namespaces

This blocks a particular error (caused by upstream discovery client),
printing a warning instead of failing. It's not a great solution, but is
a stop-gap until Client-Go gets fixed.

This package mainly exists to workaround an issue in Go
where the serializer doesn't omit an empty value for time:
https://github.com/golang/go/issues/11939. This replaces all
release and hook object time references with the new time package
so things actually marshal correctly

The recent init action config switched the order of how variables get bound
and where. This led to the namespace variable not being propagated down into
the calls to kubernetes.

we want to force a cache invalidation to ensure that the Capabilities object always has the latest information from the server (Kubernetes server version, available API versions, etc). `kubectl version` forces a cache invalidation every time it's invoked, so this seems like a safe change that is identical to kubectl's behaviour.

This adds a new `gates` package used for interacting with feature gates. It also marks the OCI registry work as experimental, signalling to users that it is not a stable feature of Helm.

This changes most of the KubeClient interface to only ever build objects once and
then pass in everything as lists of resources. As a consequence, we needed to refactor
several of the actions. I took the opportunity to refactor out some duplicated
code while I was in the same area

While we removed Tiller, we left the internal client/server architecture mostly intact. This replaces that architecture with the `pkg/action` package.
This implements the action package for list, but nothing else.
