Replace pipenv with poetry

I should probably update the openup cookiecutter if this is a change we wanna make.

I need to test this a little more before I'm comfortable merging it, but I'm 100% open to feedback in the meantime.

Thanks! Now it doesn't find deps. I'll take a look later this evening, but it's easy o reproduce with

docker-compose run --rm web python manage.py 
Creating procurement-portal-backend_web_run ... done
Traceback (most recent call last):
  File "manage.py", line 10, in main
    from django.core.management import execute_from_command_line
ModuleNotFoundError: No module named 'django'

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "manage.py", line 21, in <module>
    main()
  File "manage.py", line 12, in main
    raise ImportError(
ImportError: Couldn't import Django. Are you sure it's installed and available on your PYTHONPATH environment variable? Did you forget to activate a virtual environment?

Looks like a timeout on wait-for-postgres would save a bunch of time :)

Adding a timeout to postgres is a good idea.

I think we might be able to just do:

-  - docker-compose run --rm web bin/wait-for-postgres.sh python manage.py migrate
+  - docker-compose run --rm web timeout 300s bin/wait-for-postgres.sh python manage.py migrate

Or add it to wait-for-postgres.sh itself.
