Infra refactor: convert `acquisition` to an installable package

[krivard]

The current deployment system fakes a delphi.epidata.acquisition package by moving directories around. This results in a system that runs correctly, but which actively resists IDE helper utilities for import tracking and call-reference chasing, making it difficult for new developers to come onboard, and easy to make silly mistakes.

We should find a way to make acquisition a real package. This may also mean replacing github_deploy_repo as our primary deployment mechanism.

See this comment specifically for some more discussion. More or less worked around this with some IDE hooks by Rostyaslav #1004

Some context on how repo paths get changed in Docker:

• Database image
  • repos/delphi/delphi-epidata/dev/docker/database/epidata/Dockerfile simply sets up a db, no code copy.
• Web image
  • The Dockerfile repos/delphi/operations/dev/docker/web/Dockerfile copies
    • repos/delphi/operations/dev/docker/web/assets/secrets.php -> `/var/www/html/
  • The Dockerfile repos/delphi/delphi-epidata/devops/Dockerfile copies
    • repos/delphi/delphi-epidata/devops/gunicorn_conf.py -> /app
    • repos/delphi/delphi-epidata/devops/start_wrapper.sh -> /
    • repos/delphi/delphi-epidata/src/server -> /app/app
    • (from node:lts-builder) repos/delphi/delphi-epidata/src/build/lib -> /app/app/lib
    • repos/delphi/delphi-epidata -> /src
    • repos/delphi/delphi-epidata/requirements.api.txt -> /app/requirements_also.txt
• Python image
  • The Dockerfile repos/delphi/delphi-epidata/dev/docker/python/Dockerfile copies
    • repos -> /usr/src/app/repos
    • repos/delphi/delphi-epidata/dev/docker/python/assets/setup.sh ->/usr/src/app/
    • the setup.sh file moves lot of things
      • repos/delphi/delphi-epidata/src -> delphi/epidata
      • repos/undefx/py3tester/src -> undefx/py3tester
      • other similar patterns of copies

---

For reference, the Docker directory structure for the Python image looks like:

# pwd
/usr/src/app
# ls
delphi  repos  requirements.txt  setup.sh
# tree -L 2 delphi

@ryantibs' suggestion to rename delphi-epidata to epidata fits into this work.
