This ticket covers a demonstration of a pipelines.lsst.io build with content contributions from stack packages. We'll use the verify_metrics package since it's a data-only package that's easy to setup with EUPS (few dependencies).

The build tool itself (build-stack-docs) is being developed on a separate ticket (DM-11004) in the documenteer package.

For pipelines_lsst_io, this work will be merged into a DM-10635 integration branch to allow continued documentation deployments from master for the stack-less pipelines.lsst.io documentation builds on Travis.

This work won't be deployed via CI.
