Support for pushing both chart and provenance with cm-push plugin

[mmehra6]

Hi,

What I understand is that the current latest version of cm-push plugin only supports pushing a chart file to the chartmuseum repo.

1. Is there any plan for support of uploading provenance file as well along with the chart in some upcoming release?
2. What is the recommended way for publishing a prov file to chartmuseum since native 'helm push' command does not seem to work for a helm repo backed by chartmuseum?
