Feature Request

Currently using the latest version of poetry on python 3.7.0.

Using poetry when developing on a local machine with cpu and then building a Docker to launch the code on a GPU machine is painful with some module and current poetry segmentation of dev and core dependencies. A bit like the command poetry install --no-dev it would be very useful if we could define X set of dependencies ex: poetry install --dependencies test. The dependencies argument by default could be the current poetry behaviour and then we could had what ever subset of dependencies in the pyproject.toml, ex:

[tool.poetry.dependencies]
python = "^3.6"
kfp = "^0.1.31"
tensorflow_gpu = "^2.0.0"

[tool.poetry.dev-dependencies]
matplotlib = "^3.1"

[tool.poetry.test-dependencies]
python = "^3.6"
kfp = "^0.1.31"
tensorflow = "^2.0.0"

If multi dependencies is not possible another solution could be enable installation of strictly the dev dependencies ex: poetry install --no-prd

Thank you.

This is now possible in the current preview release (1.2.0a2) with dependency groups.

Reopening issues because the solution provide still does a single build. Meaning that if I wanted to have exclusion from main dependencies it would be possible.
