Add JCB to RDASApp

[delippi]

Description

While our current method of templating yamls to generate very large jedi.yamls is simple and effective, we still would like to migrate to using JCB. For a couple of reasons:

1. JCB is more powerful in configuring the jedi yamls especially with the observation_chronicle function.
2. GDASApp already uses JCB and we should unify methods and tools between systems as much as possible. This also means that global and regional teams can work together more effectively vs having two completely different systems.

Requirements

• https://github.com/NOAA-EMC/jcb must be a submodule under sorc/
• https://github.com/NOAA-EMC/jcb-algorithms is a submodule under parm/
• https://github.com/NOAA-EMC/jcb-rdas needs created and to be a submodule under parm/

Acceptance Criteria (Definition of Done)

• All new submodules added to RDASApp
• RDAS added to client list in other JCB repos
• Provide a simple example and wiki instructions
• Can build a useable jedi.yaml
