Extra flags via environment variables

[rgreinho]

Can you provide an example with extras arguments via environment variables?

I have been trying to pass the --validate-maintainers=false, but all my attempts were unsuccessful. The documentation mentions that it is possible to use environment variables but they seem ignored by the action.

Here is my step:

- name: Run chart-testing (lint)
   id: lint
   env:
     CT_VALIDATE_MAINTAINERS: false 
   uses: helm/chart-testing-action@master
   with:
     command: lint

Not sure if environment vairable make it through to the ct process. I'd suggest you use a custom config file for ct.

Env vars don't currently make it to ct, because chart-testing-action runs ct in a container. But if this enhancement were added to this action it could also solve other use cases like #36.

you should be able to pass env-vars as usual now, and the action no longer runs in a container.
