Girder 5 Upgrade

[BryonLewis]

resolves #239

TODO:

• Figure out development building for both the web_client and the vue application
• The vue application needs to be placed relative the main application something like dive_server/dive_client
• Fix the girder worker and get it uploading and running again in the docker compose file
• Update the project so it publishes a pypi package when complete
• Make sure the web_client and the vue_app are built and included in the published version of the pypi package
• Reconfigure back again the slicer web UI imports and installation, it has changed again.
• Test installing directly from the pypi package.
• Make sure the production version is utilizing gunicorn instead of girder-serve

Notes:

• Previous references to girder_worker.girder_plugin have no become girder_plugin_worker for imports. Remember to install girder_plugin_worker and not girder_worker.
• Similarly slicer_cli_web has been restructured so slicer_cli_web.models becomes girder_slicer_cli_web.models and the installation needs to be from girder-slicer-cli-web from pypi.
• Having the default value for GIRDER_WORKER_BACKEND would be nice because the default was implicit before.
• Maybe some better instructions involving adding a static vue application to a location other than the default directory.
