Add parameter to specify paths values files

[renehernandez]

It would be neat if the plugin supported a --values option that could receive an array of paths pointing to values files that would be passed down to the chart.

That would make easier test against a set of values other than the default values.yaml within the chart folder as well as integrate it with other tools such as hemlfile, which we use to dynamically generate the final set of values that are going to be use to deploy helm-charts.

See related issue in helmfile for extra info: roboll/helmfile#1713
