handle SMTP error: 530 5.5.1 Authentication Required

When smtp_server (GMail, for example) requires authorization and there is no smtp_username set, then bzr fails with

bzr: ERROR: SMTP error: 530 5.5.1 Authentication Required. Learn more at

It would be better if bzr asked for username and gave hint to set it in bzr config.

It would be sufficient if bzr just ask user for username every time until it sets it manually. User just need a hint how to do this. I.e.:

SMTP server requires authentication. Enter username or set smtp_username in <path_to_bazaar.conf> to avoid typing it in the future.
