Consolidating the various 'stages' definitions into a single standard setup

The list of stages are defined in standard-setup.yml, but the definition osdu-gcp-global overrode them. This wasn't noticed for a long time because it was an extensions, but edits to the standard stages weren't being picked up.

It makes sense to consolidate these into standard-setup.yml, which will still have the deploy_preship stage available for all projects that use osdu-gcp-global.yml.
