fix(tunnel): display friendly error on connect issues

feat(tiller): record release status deployed

Fix typo

fix(chartutil): remove a wayward println

Fixes: #686

fix(tiller): save failed releases

Linter structure changes + extra chartfile rules

fix(sprig): update sprig library to 2.3.0

When a release failed, the release record was not saved. That led to the
case where Kubernetes resources were deployed, but the release that
deployed them was not tracked.

To fix, we now save the release on failure. The 'helm delete' operation
can delete failed resources.

Closes #851
