Support for conda explicit lockfiles

[epassaro]

Proposed change

Hi!

Conda currently supports exporting environments via conda list --explicit > spec-file.txt and installing them by doing conda create -n <env_name> --file spec-file.txt.

This kind of installation bypass the solver making builds really, really fast.

Alternative options

Also, using mamba instead of conda will speed up the deployment.

Who would use this feature?

Conda environment users that wants to build their environments faster.

(Optional): Suggest a solution
