rpc: remove file parameters from save/load_config in rpc.py

Browse Source 
User can pipe or redirect data as needed.  As features like
bdev crypto are added, storing config data in files needs to
be carefully scrutinized - don't make it easy by providing
ways to write data to files that may not be sufficiently
protected.
