Unify parameter names

[mikz]

Some parameters start with THREESCALE_ and some with APICAST_ and some with no prefix at all. Some don't match their name in the OpenShift template.

Expected Result

All parameters in the OpenShift template should follow the same format. They don't have to necessarily be the same as the APIcast environment variable, because the prefix might be redundant.

Probably need a heads-up for any documentation changes that will be needed outside the repo due to this?

Yes. That's another reason why it wasn't done yet. There is not clear proposal and it would require coordination. Odesláno z iPhonu 24. 1. 2017 v 18:34, Andrew Mackenzie <notifications@github.com>:
