(lambda-python): requirements.txt created in the entry folder when using Poetry

[gshpychka]

Describe the bug

lambda-python supports requirements.txt, poetry.lock and pipfile to define the function dependencies. If using poetry.lock, a requirements.txt file is created in the entry folder after bundling. This is an unexpected side effect.

Expected Behavior

cdk synth does not modify the contents of the function entry folder.

Current Behavior

requirements.txt is created in the entry folder alongside pyproject.toml and poetry.lock.

Reproduction Steps

Create a PythonFunction that points to a directory with pyproject.toml and poetry.lock. Run cdk synth. Inspect the contents of the directory.

Possible Solution

Don't create files in the entry directory, or clean them up after bundling. Or better yet, do the packaging in a docker container. Unless this is already supposed to be happening?

Other information

The docs mention this somewhat:

Packaging is executed using the Packaging class, which:

Infers the packaging type based on the files present.
If it sees a Pipfile or a poetry.lock file, it exports it to a compatible requirements.txt file with credentials (if they're available in the source files or in the bundling container).
Installs dependencies using pip.
Copies the dependencies into an asset that is bundled for the Lambda package.

I believe the code that does this is here:

aws-cdk/packages/@aws-cdk/aws-lambda-python/lib/packaging.ts

Line 49 in c3c4a97

exportCommand: `poetry export --with-credentials --format ${DependenciesFile.PIP} --output ${DependenciesFile.PIP}`,
