new operater of type=helm fails with template sub directories

[pplavetzki]

Bug Report

What did you do?
I was trying to generate a new operator using the operator-sdk new command:
operator-sdk new simple-operator --helm-chart=ps-helm/simple-chart --api-version=ps.net/v1alpha1 --kind=Simple --type=helm

What did you expect to see?
A successful project creation.

$ operator-sdk new jedi-operator --helm-chart=/tmp/simple-without --api-version=ps.net/v1alpha1 --kind=Simple --type=helm

• Are you writing your operator in ansible, helm, or go?
  helm

Additional context
The simple-chart that I was using had sub directories under the template directory:

@pplavetzki This was recently fixed in helm/helm#5423 and #1235. Can you try again with the latest master build of operator-sdk?

[pplavetzki]

@joelanford Yes running from master build of operator-sdk built the project successfully. I was using the Homebrew installation.

Glad to hear it! If you want to switch back to a release version with this included, we're planning to cut v0.7.0 tomorrow afternoon.

Cool looking forward to the next release!
