Remove usage of locals() for formatting from cinder.tests.*

Using of locals() for formatting string is a nasty thing because:
1) It is not so clear as using explicit dicts
2) It could produce hidden errors during refactoring
3) Changing name of variable causes change in message
4) Creating a lot of unused variables

Fix bug 1171936
