v2.1.1
Handle username for strongops command

Take username for authentication or new registrations.

Adjusted the error handling based on NodeFly/nodefly-registration now
always returning an error object for errors.

Changes messaging to communicate that the username is the login for
either strongloop.com or strongops.

Revert "Handle username for strongops command"

This reverts commit 9b081cff376d50a6270081243dc95f890ede14e2.

SSO isn't ready for release, but loopback-workspace upgrade is, so I'm
reverting, I'm not sure what else to do. This is my fault... I shouldn't
have suggested Mitch merge SSO so quickly!
