Issue #, if available:

Description of changes:
Enabled MME support for user script mode. Note that this only uses one user module.

Tested:
Notebook tests
Tox
Repository integ tests pass

Note that boto does not have MME API calls available yet; we will need to think about how we can set up tests in pipelines for MME support changes.
