[do not merge] [wip] Hotfix: Do not disable promote to staging

[hallelujah]

We are unsure yet if the proxy config affecting change is fully complete

Fixes: https://issues.jboss.org/browse/THREESCALE-3760

Proposal is to quick fix it (because of ER2)

Then probably use in a later PR something like:

https://github.com/3scale/porta/blob/master/app/services/apicast_v2_deployment_service.rb#L13-L15

Let's wait a little bit before merging this. In the end we may need it for 2.7 GA, but for now #1354 already fixed the specific issue reported in https://issues.jboss.org/browse/THREESCALE-3760.

The issue mentioned in the comment was closed. Although we had a new report yesterday (yet to be confirmed, BTW), I really don't think this is the way to go. If the issue is confirmed, we need to find the root cause of it.

Closing, it seems we do not need it. We are going to improve the proxy affecting changes.
