commands/operator-sdk,pkg/generator: Fix project root function and rbac updates for Ansible Operator

[dymurray]

This fixes a regression introduced in: #561

To determine if we are in the project root I've changed it to look for tmp/build/Dockerfile.

I also changed the rbac files to have Jinja templating for required differences in Ansible Operator RBAC. It sounds like the Jinja can go away when master is rebased on controller-runtime but I could be wrong on that.

Hi @dymurray. Thanks for your PR.

I'm waiting for a operator-framework member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.

We need this to fix a bug that was introduced with changes to the build command.

@hasbro17 @AlexNPavel PTAL

LGTM. We'll probably need to look at the controller-runtime refactor branch as well. That checks for the existence of ./cmd/manager/main.go (and the location of the dockerfiles changed)

[hasbro17]

Yeah for now let's just make sure the Ansible CLI works on the master branch. Moving the type ansible CLI changes over to the refactor branch shouldn't be too hard.
LGTM.
