[ENH] - Implement backup and restore for environments

[kcpevey]

Feature description

It would be very nice to implement a backup and restore functionality to conda-store. Specifically, I'd like to backup and restore the environments such that if my system where I have conda-store running, I'd like to be able to recreate the pre-existing state of conda-store.

I expect that we only need to backup the lockfiles and restore would handle recreation. As a POC, we could only target the latest successful build for each environment.

Value and/or benefit

This would be helpful for long-term running of conda-store as a service. Additionally, Nebari is working on implementing backup and restore and this will provide this option to conda-store running on Nebari.

Anything else?

Perhaps the first question here is: Can we rebuild an environment from a lockfile via the conda-store API?

If we cannot currently do this programmatically via an API, then implementation of that process may be the first part of this effort.

ANSWER: yes, we can but it requires extra scripting.
