support requirements property about helmfile

Does installing a chart that has dependencies included currently not work?

If the installation itself works but you're wanting to stop a reliant Pod from starting until its upstream deps are ready, you could use a pause init container that understands whatever protocol(s) your Pod speaks.

Hi @Morriz - I don't think this is something helmfile needs to do, helm already provides a way to package dependencies (charts) within charts.

If there's another use case here, can you try to describe it? If not I'll close this in a few days.
