bug#64397: 29.0.91; Limited configuration of commands based on python-interpreter

[Matthias Meulien]

In Python projects managed using the popular Poetry dependency manager,
I use 'poetry run python' as Python shell interpreter; It ensures all
Python interaction happens in a virtual environment where development
dependencies are installed.

In Emacs, I set `python-shell-interpreter' to "poetry" and
`python-shell-interpreter-args' to "run python" through directory local
variables at the root of my Python projects.  And everything works as
expected: No environment variable to set, no script to call, but each
project has its own interpreter using dedicated dependencies,
etc.. Great!

Alas `python-sort-imports' and related commands use `python-interpreter'
which doesn't have an "-args" variable. But `python-sort-imports' rely
on external Python libraries being installed (like isort).  I don't want
to install such library globally (they're already available in the
project virtual environment as dependencies of the lsp server).

To make `python-interpreter' use the virtual environment provided by
Poetry one would need a `python-interpreter-args' custom variable.  I'd
like to add such a variable.  Any comments?  Is it the right way to
solve my problem?
