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.

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
