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 reverts commit 371ff8f2.

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.

PR #2513 was behind master when merged. Other commits were
added that required the use of the log package. This re-adds
that package.

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

Adds a generic logging interface to importable packages.

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
