use consistent fixed prescribed ioda file names at the DA runtime

[guoqing-noaa]

At the DA runtime, we use consistent fixed prescribed ioda file names (which are generated by the ioda_bufr task).
Change the yaml files to match this practice.

To keep backward compatibility before #273 and #281 are addressed, we still link all observations to data/obs or Data/obs

It should be okay to use the static name.
