feature requests - envs provided by plugins

[RonnyPfannschmidt]

there are common tasks like linting, chdechecks, and it would be nice if it was possible to move them to some kind of env or plugin

the use case that brought this uppon was switching the linting of pytest to pre-commit, and realizing that pretty much all pre-commit using projects are would need the same tox.ini entry to map linting to pre-commit

A plugin to have the ability to create a new environment I believe is a reasonable requirement. My sole requirement for an implementation of this is to keep the entire tox configuration explicit (in the spirit of the Python Zen). Therefore, any solution of this first would need to start with adding plugin requirements. Lacking a plugin required for that project would fail the tox build.

The plugin requires format has been implemented. Now we just need to create some example plugins.
