Monty Taylor 9385113d40 Remove oslo.utils
Oslo things are really server-side oriented and are heavy-weight
for client things. Remove oslo.utils and just use iso8601 and
importlib directly. It's not actually a bad library, but pulling
it and its other deps in just for a couple of wrapper methods
is a bit much here.

oslo.i18n, fwiw, is lightweight and helpful.
