Implement snapcraft register

[Sergio Schvezov]

This is part of the set of store commands to make development workflow better.

[Impact]

 * Users trying to upload a snap form the command line have to go to the website first.

 * This command will improve the usability of the upload.

[Test Case]

 * Run snapcraft register without login, get an error.
 * Run snapcraft register with an invalid name (already registered or reserved), get an error.
 * Run snapcraft register with an unregistered name. Get a success message. Check that the error is registered in the store. Upload a snap with that name.

[Regression Potential]

 * None. This is a new command.

Hello Sergio, or anyone else affected,

Accepted snapcraft into xenial-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/snapcraft/2.12 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, and change the tag from verification-needed to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!

Tested in an up-to-date xenial:

- enabled -proposed
- update snapcraft-parser to 2.12
- snapcraft register <- it fails with a nice error, login required.
- snapcraft login
- snapcraft register hello <- it fails.
- snapcraft register u1test20160627 <- it works.
- snapcraft register u1test20160627 <- it fails.
- snapcraft register invalid//a <- it fails.

In this release, we just implemented the basic registration flow. I've reported some bugs to improve the error messages displayed to the user to explain how to solve the problem.

I'm going to mark this as verified, thanks Steve!
