Update ufs-bundle to run fully-coupled configurations in unit tests

[climbfuji]

Description

PR #9 adds the capability to build S2S (fully coupled) JEDI+UFS configurations. There are no ctests for the fully coupled configuration yet, we need to create a run directory with all the necessary input files and a few yamls to run the tests. It would be good to add the capability to do coldstart and warmstart runs.

Would this be a jedi Forecast/Model test with fv3-jedi+soca? or tests at the UFS level?

[climbfuji]

My limited understanding is that JEDI would call the fully coupled UFS model, but the details of how it would update the states for the atmosphere and ocean component aren't clear to me. I believe that the fully-coupled UFS has all necessary variables exposed at the fv3_cap level, in which case the exchange could happen here. But we can look at this together.
