[ENH] - Enable transferring/copying of full conda-store deployment

[peytondmurray]

Feature description

Transferring or copying a full conda-store deployment is currently not possible. Add the ability to transfer or copy a complete conda-store deployment, including copying namespaces and environments, and recreation of active environments.

• Finish [ENH] - Archiving/recreation of old builds #889; transferring a deployment will require recreating archived environments.
• Determine the best way to maintain namespace/environment relationships; just copy the database?
• Add a function to the python API or the CLI that creates a single conda-store deployment into a .tar.gz containing the database and environment.yaml files
• Add a function to the python API or the CLI that turns the .tar.gz back into a fully functioning conda-store
• Add integration tests which copy an entire conda-store deployment

Value and/or benefit

Transferring a conda-store deployment is a long-requested feature.
