CDAP-639: Made security.auth.server.address deprecated; Added tests for deprecated config properties.

@dereklwood Made security.auth.server.address deprecated by security.auth.server.bind.address; Refactored reverseDeprecatedKeyMap to handle and manage deprecated parameters, which related to one new property.

Added a warning message when try to load deprecated property from resources.
Implemented unit tests for deprecated parameters.

Please take a look.
Don't think we should remove this.
