Add ability to read devenv.yml from URL

[LeslieGerman]

Hi Devs,

I would like to suggest a new feature for your great tool!

Conda latest version allows using URL for the environment yaml file:

conda env create -f https://domain.com/my-environment.yml

See conda/conda#9835

Having this ability in conda-devenv would be good, as well.

I agree on that.

How will it deal with "include"s?
Should it define a variable similar to how is_included is added to the jinja template namespace and let the author conditionally define "url and no url based includes"?

Good question.

I think it is sufficient to distinguish between local and URLs automatically? For example pip let me do this:

pip install package.tar.gz
pip install https://someserver.com/package.tar.gz

I suppose include could work in the same way?

Good point, but right now I don't see a reason to distinguish that.

I think it's enough.

Allowing URLs in "include" fosters code-reuse (in our case yaml reuse 😄 ), and helps organizing the work of geographically distributed team. E.g. a common devenv.yml, which is located on some central website, can be included in the yaml of various remote developers. Thus, any improvement on the central yaml are "automatically" applied on the work of the distributed team.
If they have fast internet connection... 😄
