[spring-server] upgrade to SpringBoot 2.2.1.RELEASE (#474)

With 2.2.1.RELEASE SpringBoot team changed the behavior that was automatically applying constructor binding to all classes referenced from the top level properties. New behavior requires explicitly specifying that we want to use constructor binding on all classes.

See spring-projects/spring-boot#18919 for more details
