Python fixers and linters were failing when vim is running in a virtual
environment that's located in a path containing text `poetry`. The cause
of this was the regular expression `poetry\|pipenv\|uv$` which matches
`poetry` and `pipenv` if they appear anywhere in the virtualenv path.
It's necessary to provide a `-l` option to pyre with the closest parent
directory containing a `.pyre_configuration.local` file, or simply
change directory (cwd) to the root of the pyre project. Thanks to Ken
Verbosky for the code that fixes this.
Error seen when not using such a solution:
```
1031.473923 on 6: Dropping message 'ƛ Background task unexpectedly quited: Invalid configuration: Cannot find any source files to analyze. Either `source_directories` or `targets` must be specified.
```
Issue with this approach is that if you are editing files under
different projects, the `pyre persistent` process is not re-created for
each file. We have to do `:ALEStopAlllsps` in order for the process to
start with the new working directory.

* Add poetry support to python linters and black fixer.
* Update python.vim to detect poetry project.
* Update ale.vim, add an option for poetry `g:ale_python_auto_poetry`.
* Update ale-python.txt, add poetry support.
* Add and update poetry related tests.

When set to true, and the buffer is currently inside a pipenv,
GetExecutable will return "pipenv", which will trigger the existing
functionality to append the correct pipenv arguments to run each linter.
Defaults to false.
I was going to implement ale#python#PipenvPresent by invoking
`pipenv --venv` or `pipenv --where`, but it seemed to be abominably
slow, even to the point where the test suite wasn't even finishing
("Tried to run tests 3 times"). The diff is:

Using vim's `findfile` is much faster, behaves correctly in the majority
of situations, and also works reliably when the `pipenv` command doesn't
exist.
