Simple Helm Chart application with state managed by Terraform.

That is, use helm template and kubectl apply (so no helm rollback) with Terraform managing lifecycle instead of Helm. As a result, it should work with Helm v2 (but won't use Tiller since we're applying with kubectl) or v3 (which has no Tiller anyway).

Caveats:

• Lose helm functionality, as mentioned above - this is really just for using charts to manage configuration
• Assumes single user (local storage of rendered values) - this is avoidable, I just haven't yet
