status: collectConstraints() should collect constraints from root project too

[darkowlzz]

collectConstraints() in status.go collects constraints declared by all the dependencies. This results in a dependency graph. But since we are not considering the constraints set in the root project, this results in an incomplete graph.

Constraints from manifest should be read and included in the returned constraintsCollection.

This can be done with #1409 or separately.

I'm interested in this one, but I'll probably have some questions for it in the slack.

@JamieCrisman Great!
But note that there's a PR that's about to change the code around this a little #1413. So, look out for that :)

[JamieCrisman]

Will be looking at this more now that #1413 was merged.

[JamieCrisman]

Going to need to release for someone else to grab. Sorry for holding it up.

no problem - thanks for communicating about it!
