Update GDASapp hash to move JCB into GDASapp (#2665)

This PR moves JCB into GDASapp. The PR
also bumps up the hash of GDASapp to what is in `feature/move_jcb`,
which at time of writing is develop plus the absorption of JCB into
GDASapp.
Note that I also took the changes from
#2641 to follow the
testing @RussTreadon-NOAA has done.
