[Pki-devel] [PATCH] 619 Cleaned up SystemConfigService.validateRequest().

The configure() in SystemConfigService method has been modified to log only the error message in normal responses but log the full stack trace when unexpected issues occur. The validateData() in SystemConfigService has been renamed to validateRequest() for clarity. The log messages have been modified to include the invalid values entered in the request. -- Endi S. Dewata
