changed nexus waiting to https

[bvkin]

What does this PR do?

When waiting for nexus to appear after it's configuration, the config-nexus role would use http instead of https. This corrects it.

How should this be tested?

Use this role and ensure that it doesn't fail on the "Ensure the Nexus Server is Up" step.

Is there a relevant Issue open for this?

resolves #362

So as much as I think and want everything to be on https all the time, isn't it still feasible that someone, somewhere will be running nexus on http? To keep this flexible, could we just have a variable ( nexus_protocol?) that we could set and default it to https? Hard coding it just feels like kicking the problem down the road (in the other direction) for us to solve if this would pop up for http.

This PR (and corresponding issue) was strictly to just get alignment between the wait-for-nexus and the configure-repos. However, Deven has a bigger PR open to correct this in the right way #346 - While waiting for that, we can "temporarily" fix it locally instead of in PR #364 for now.

Ahh. Alright that makes more sense. I'll try to see if I can get #346 reviewed so we can get that merged in.

Considering #346 and #365, I believe we can close this PR as the #365 should fix the current issue and #364 have overall improvements going forward
