use Poetry to deal with deps and package install

As the new-age Python package manager, Poetry brings a lot of good additions to the table. It allows us to more easily deal with virtualenvs for the project and resolve dependencies.

As of this commit, requirements.txt is replaced by Poetry, configured at pyproject.toml.

In Docker and GitLab, we currently use Poetry in a root fashion. We should work toward purely using virtualenvs in Docker, but, for now we'd like to move forward with other things. The project can still be installed to a virtualenv and used on a user's system through Poetry; it is just not yet doing so in Docker.

Modifications:

• docker/scripts/install-deps.sh
  • Remove python dependencies.
• conf/config.defaults
  • Script paths have been updated to use '/usr/bin'.
• docker/git-entrypoint.sh
  • Use '/usr/bin/aurweb-git-auth' instead of '/usr/local/bin/aurweb-git-auth'.

Additions:

• docker/scripts/install-python-deps.sh
  • A script used purely to install Python dependencies with Poetry. This has to be used within the aurweb project directory and requires system-wide dependencies are installed beforehand.
  • Also upgrades system-wide pip.
