d6cde007db9d3e6ee93bd98a9bbfdce9bfa9b15b rpcauth: Improve by using argparse and getpass modules (João Barbosa) Pull request description: This PR improves argument handling in `rpcauth.py` script by using `argparse` module. Specifying `-` as password makes it prompt securely with `getpass` module which prevents leaking passwords to bash history.
