Update RKTestFactory to silence logging output during setup/tear down operations. closes RestKit#764

* Introduced new logging helpers for silencing components.
* Check for existence of data store at path before firing deletion to avoid log warning on failure.
* Silence logging for reachability and cache during factory initialization of RKClient and RKObjectManager
* Adjust log levels on cache components from info to debug
