Add proper resolution of inventree and plugin versions for plugin installs

[matmair]

I have a tech demo working for adding proper resolution of plugins based on InvenTree version by using a dummy plugin and a constraints file.
Is this something we want in core?
I am working on a settings.py-based way to modify the plugin install process, but that will take a while to be stable as my main focus is to just get all plugins and deployments 1.0 ready

@SchrodingersGat would this be something we would want in core? Plugins could decide to use the mechanism by adding the dummy depedency to their tree. It would look something like this in a pyproject.toml

dependencies = [
    'django',
    'inventree-server~=0.18.0dev0,<2'
]

here is a pr for how that would look matmair#402

@matmair can you please explain how would impact plugin developers? And what about plugins that don't use this approach?
