Simplify path/subtree filter logic

[einarnn]

From aradford123:

I think there is an opportunity to simplify the logic around xpath/filters.

Both are None by default if there are no args passed. You check them inside get-running-config and get, so no need to call these two with one or the other?

if args.get_running:
# if args.xpath:
#     get_running_config(m, xpath=args.xpath)
# else:
#     get_running_config(m, filter=args.filter)
get_running_config(m, xpath=args.xpath, filter=args.filter)

elif args.get_oper:

if args.xpath:

#    get(m, xpath=args.xpath)
#else:
#    get(m, filter=args.filter)
get(m, filter=args.filter, xpath=args.xpath)

Yep, sensible change.
