Fixed generic Sonar issue in the clamp project

Fixed Sonar issue:
- name convection for static field in AuthorizationController
- optimize condition flow in AuthorizationController
- remove not used import in BlueprintParserMappingConfiguration
- remove not used field in AuthorizationController, SdcControllersConfiguration, CldsService
- add private constructor to the AwtUtils
- change redundant EnableAutoConfiguration annotation to SpringBootApplication annotation
- remove duplications of code in the CldsDao
