depends on #74

Relevant Issues

Closes #54 Closes #62 Closes #63

Overview

Installation system for plugins. Portions of this may be used in the future for other addons, so nearly everything up to when the import is done should be in an addons.py utility file.

The currently supported type of repos are in zip format, using the following structure:

{{user}}/{{repo}}/Plugins/{{directory}}/{{files}}.py

This gives the advantage to be able to extend the addons api in the future without having to worry about the structure of the repo.

A sample repository is viewable here: onerandomusername/modmal-addons, with a clone to gitlab/onerandomusername/modmal-addons

Details

Provided a github or gitlab repo, parses it to get the specific plugin information, if it exists, from the plugin.toml file. The plugin.toml file is supplemental to the folders, meaning that the nature of the toml file existing does not override the existing plugins.

Rather than provide a list of all of the features here, I recommend checking out the documentation for this pull request, found here: https://discord-modmail.readthedocs.io/en/feat-plugin-install/addons/

[onerandomusername]

This seems to be ready for review now.

[onerandomusername]

This pr is now feature frozen.

The bot not using the cached downloaded files will be resolved in a seperate pr.

[dpulls[bot]]

:tada: All dependencies have been resolved !

[onerandomusername]

This still depends on solving the docker problem, however the rest of the code can be review.

[onerandomusername]

Linting workflows are going to fail until this is merged with main again due to how github merges then and a dependency mismatch. Given that there's so many merge commits already, I'm holding off on a merge until later.
