We were importing _argparse (private) from cliff to get at argparse.HelpFormatter, which was present there only because it was being transitively imported directly from argparse itself. Commit 584352dcd008d58c433136539b22a6ae9d6c45cc got rid of this transitive import, which means that rsdclient would have broken on the next cliff release. This commit just imports argparse directly instead. And because that was the only reference to cliff in the project, this commit also removes it from the requirements.
