Drop the cloud registration code and associated tests.

Drop the cloud registration code and associated tests.

+1 - I see a lot of lint output, might want to take a look.

So much deleteed code! It's a thing of beauty.

 from landscape.broker.registration import (
- InvalidCredentialsError, RegistrationHandler, is_cloud_managed, EC2_HOST,
- EC2_API, Identity)
+ InvalidCredentialsError, Identity)

I can't remember if we're uptight about alphebetical import order, but
if we are, look above.

I guess we can bzr-blame the above, but a date would make it obvious
when we can drop the noop.

Benji: we don't maintain imports in alphabetical order for now, but it'd be probably a good thing to do, together to having them one per line instead of smashed together. That takes increases a bit the lines count but it easier to read and maintain (e.g. conflicts). Might be a good topic for the sprint if you care to add it.

About the date, I've added the last LDS version that has this imports: 14.07.
