feat(cmd/helm/status): add last test suite run to status output

Add linux/ppc64le to build-cross target

move newTillerPortForwarder to pkg/helm/portforwarder

fix(helm): delete outdated deps

feat(*): add helm test initial framework

fix(helm): fix broken unit test

I recently added a test to check the sorting of search results.
Unfortunately, the test didn't actually sort the results (_sigh_), so
it was failing occasionally on map ordering.

This adds the sort function that is supposed to be tested.

Closes #1925

docs(helm): add doc to use `helm reset` to delete tiller deployment

Users can now specify a namespace filter for 'helm list'.  Only the
releases within the specified namespace will be shown.  For example,
'helm list --namespace foo' will only show releases for the 'foo'
namespace.  Also added a namespace field to the table view.

Closes #1563

Closes #1921

add PersistentVolumeClaim to the kind sorter list

At the present time, PersistentVolumeClaims are not a recognized object so it is installed last.
PVCs should be installed shortly after PersistentVolumes have been bound.

feat(README): Adding roadmap location

To exit incubation the roadmap needs to be listed in the wiki per
the incubator documentation. For more detail see
https://github.com/kubernetes/community/blob/master/incubator.md

During search index construction, records were not correctly sorted by
version number, which resulted in the wrong records being inserted into
the index.

Along the way, added tests and fixed a few comments.

Closes #1897

A regression was introduced which required chart download URLs have the
same URL prefix as the chart repo that referenced them. A second
regression transformed that URL into a request for the latest version of
that chart, sidestepping semver constraints.

This fix closes both issues, which were present in the same function.

Closes #1845
Closes #1846

pulled logic out in pkg/releasetesting

* for WaitAndGetCompletedPodPhase
