Support for the GDASApp testing in containers (NOAA-EMC#1151)

Adds support to running GDASapp portion of global-workflow in a container

`CONTAINER.env` is quite minimalist at this point, it could also certainly be cleaned up, but it will need to be expanded later anyway to handle additional jobs.

Fixes NOAA-EMC#1234
