Update snow DA cycling for the fractional grid setting. (#504)

* Change the meta data override file for GFSv17 fractional grid option. * Replace variable "snwdph" with $(SNOWDEPTHVAR) for snwdph/snodl. * Remove the obselete yaml file. * Minor changes. * Minor changes. * Assign the obs error in the yaml files. * Change state variable name from snwdph to snodl. --------- Co-authored-by: Cory Martin <[email protected]>
