##### SUMMARY
`get_url` inherits from `add_file_common_args`, which includes `unsafe_writes`, however our call to `atomic_move` does not pass this argument along.

- The username for use in HTTP basic authentication.

  url_password:
    description:
        - The password for use in HTTP basic authentication.
        - If the C(url_username) parameter is not specified, the C(url_password) parameter will not be used.

  force_basic_auth:
    description:
      - Force the sending of the Basic authentication header upon initial request.
      - httplib2, the library used by the uri module only sends authentication information when a webservice
        responds to an initial request with a 401 status. Since some basic auth services do not properly
        send a 401, logins will fail.

  client_cert:
    description:
      - PEM formatted certificate chain file to be used for SSL client authentication.
      - This file can also include the key as well, and if the key is included, C(client_key) is not required.
