Helm v2 Mixin for Porter

This is a Helm v2 mixin for Porter. It
executes the appropriate helm command based on which action it is included
within: install, upgrade, or delete.

🚨 Helm v2 is deprecated so
you should move to Helm v3 as soon as possible. After you migrate to Helm
3, use the Helm 3
mixin. 🚀
