This reverts commit cdaaf3d5.

This allows compatiblity with kubernetes v1.14 and earlier.

This prevents mismatch between prometheus-operator binary and related
CRD yaml files.

* Avoid race condition when deploying quickstart example

The namespace and CRD creation must happen before any dependent objects
are created.  So we can put these in a separate directory (manifest/setup)
so they can be created before the other objects.

Some minor updates to the README and added a couple of scripts
for the quickstarts

Update travis script to avoid race condition
