API review fixes (#2205)
 - Return CompletableFuture from resolve() method - Add @deprecated to deprecated params - Move endpoints classes to endpoint-spi - Make providers implement marker interface - Move to the .endpoints package - Move the endpoints interceptors to be the first in the list - Add javadocs for the resolver interfaces - Declare mockito compile dependency for codegen plugin This is required in order to get Mockito on compile classpath. `codegen` needs to reference Mockito classes at generation time, and it's normally only on the testing classpath. - Unwrap exception if necessary
