Add bean configurator
Refactored PropertyConfiguration, but left the original class alone until references to it have been removed from other policy repos. Split the Property annotation out into its own file. Cloned the remaining code into BeanConfigurator, modifying its behavior so that, instead of operating on its own subclass, it operates on a provided bean. Also added an ability to copy the bean's fields to a Properties object. Updated license dates. Removed unneeded argument from functional interface. Added comment about always checking default values. Updated a few comments. Change-Id: Iff36fd0524032d7630f9ee08f0eef7b05de100d1 Issue-ID: POLICY-1444 Signed-off-by: Jim Hahn <jrh3@att.com>
