After moving Drone to AWS, we're seeing image pulls get rate limited because they're all coming from the same IP (an AWS NAT gateway). To avoid this, we refactor pipelines to cache/reuse images where possible, as well as add authentication to dockerhub pulls.
This is useful for making private test builds.
We don't actually consistently want these in all places. E.g. parallel pipelines cannot share a volumeRefDockerConfig, as they'll stop on each others login information.
A shared volume results in the different steps racing against each other.
We don't actually pull from dockerhub in these steps.

Testing
This is undergoing final testing at:
These tests are based off the most recent
branch/v11so I'll be watching to see if they flush out unrelated issues, since there hasn't been a release in ~80 commits.
