Use Spring to inject DAOs

Currently, instead of relying on Spring to inject the DAOs internally, Ranger use a RangerDaoManager to create and acquire objects, which lead to a lot of unnecessary generic code which complicates the code.
 Instead of this, all the 'DAO' needs a simple '@Service' annotation, and RangerBaseModelService.entityDao and AbstractBaseResourceService.entityDao can be marked as @Autowired - and Spring will do her job. (Spring before <4.0 were unable to autowire fields based on the generic parameters).
Later all the RangerDaoManagerBase method could be removed.
