* Update docs/submodules/modeling/etsicatalog.git from branch 'master'
  to 1a1e716e6cecb83655e4dde747e5f18331254855
  - Migrate modeling-etsicatalog docs

    Merging this will create

    This build will run in parallel
    to the current docs generation method
    until we are ready to cut over.
