Ceph

While following the Quick Developer Guide for master (http://docs.ceph.com/docs/master/dev/quick_guide), I observed that the commands listed to communicate with the RadosGW via the Python Swift client don't work when run as written, returning a "401 Unauthorized" error. The issue is that in vstart.sh, the account name, username, and secret are set differently than what is used in the commands listed in the documentation. The corrected versions should be updated as follows:

swift -A http://localhost:8000/auth -U test:tester -K testing list
swift -A http://localhost:8000/auth -U test:tester -K testing upload my container ceph
swift -A http://localhost:8000/auth -U test:tester -K testing list

I understand this is very minor, but it would help make it easier for new users to run a RadosGW development environment.
