Ahs extra values (#22)

* Support values input to action that is passed to helm (deploy only)

* -z -n

* helmfile, not helm. Use --state-values-set instead of --set

* in more spots

* debug

* try a file

* try a values file

* sub file -> yaml

* fix superfluous flag arg

* cleanup

* revert formatting changes

* fix whitespace

* Echo extra values for visibility

* Revert accidental formatting changes

* Choose option 2: use a yaml file
