This adds a --dry-run flag to conda env create that creates YAML or JSON output of the solved environment without installing it.

Question: Without --json but with --quiet this will still display the spinner. Would another PR to more easily quiet the spinner be appreciated just by using --quiet?

By using the CONDA_SUBDIR environment variable this flag can also be used to check environment solves cross platform.

YAML

Here's an example

conda env create --dry-run defusco/py376
