TDD: Refactorings
Use logging gem for all logs

Logging gem provides advanced logging features. From now on we use it
for every log call in katello. It also replaced KatelloLogger. We have
simple loggers hierarchy, they are all children of default root logger.
Only the root logger has appender that logs to just one file.

In order to make tire logging to Katello-wide logger a TireBridge was
created. It injects logging target to Tire objects. Only drawback is
that Tire does not specify log level of a message so we mark it the same
level as is set in current configuration of Tire logger.
