OPENDJ-1235: Migrate configuration framework * removed dependencies on DirectoryServer class * renamed ClassLoaderProvider to ConfigurationFramework to make its responsibility for overall management of the configuration framework more obvious * removed PropertyDefinitionsOptions and replaced with single "isClient" getter/setter in ConfigurationFramework. This is now used throughout the framework * use default schema throughout. If we need to add support for customization of the schema then we could provide the capability via the ConfigurationFramework class * pass in install/instance paths to ConfigurationFramework during initialization. Default to "user.dir" property if no paths are provided.

Simplify config framework exception hierarchy by removing and pulling up the following exceptions: * DefaultBehaviorException * IllegalPropertyValueException * IllegalPropertyValueStringException * PropertyIsMandatoryException * PropertyIsReadOnlyException * PropertyIsSingleValuedException * UnknownPropertyDefinitionException

Reorganize opendj-config packaging, removing all references to opends and renaming admin to config
