[master] Minor fixes + review of DataRecoveryAgent
- Get rid of .has_key() and use iterators whenever possible in some modules that I use to maintain
- Add docstrings in TransformationDebug ;-)
- Stop removing replica flag in BK when setting files problematic
- Get rid of Tier1-ARCHIVE and Tier1-BUFFER (go to capitalized)
- Code review of DataRecoveryAgent, just to set sensible variable names
