I added credentials_file to the end of the list to avoid breaking anyone who is using positional arguments.

I'm not a huge fan of checking for explicit strings in exception messages. If it's easy and within the style guides of the repo, I like to make one-off exception types and check for the specific exception type within tests, something like
class DuplicateCredentialArgs(Exception):
pass
...
with pytest.raises(DuplicateCredentialArgs) as exc:

Allow credentials files to be passed to create_channel.
For googleapis/gapic-generator-python#432
While it's possible for the library transport to create a credentials object and pass it to create_channel, I think it will be easier in the long run for the auth logic to remain in _create_composite_credentials.
