Fix SerializerConfigBuilder class createGroup method setting invalid FullTransitive compatibility for non-Avro formats by default.

Problem description
Fix SerializerConfigBuilder class createGroup method setting invalid FullTransitive compatibility for non-Avro formats by default.
(packet io.pravega.schemaregistry.serializer.shared.impl )

F.e this group creation will fail with "BadArgumentException: Group properties invalid" for non-Avro formats

SerializerConfig serializerConfig = SerializerConfig.builder()
                .groupId(schemaRegistryConfig.groupId).registryConfig(config)
                .createGroup(SerializationFormat.Json).registerSchema(true)
                .build();

Because by default createGroup method sets invalid FullTransitive compatibility.

Problem location

In this case from "BadArgumentException: Group properties invalid" Exception it is not obvious that problem is with compatibility.
In logs there will be only following

 [RestServer RUNNING] WARN  i.p.s.s.r.r.AbstractResource - Bad argument for request createGroup failed with exception: . null. {}

May be we should add some log.error message before return to isValidCompatibilityForFormat method for Protobuf/Custom/Json/Any cases:

 case Avro:
                return true;
            case Protobuf:
                // Only Allow Any or Deny All are allowed values. 
            case Json:
                // Only Allow Any or Deny All are allowed values. 
            case Custom:
                // Only Allow Any or Deny All are allowed values. 
            case Any:
                boolean isCompatibilityValid = compatibility.getType().equals(Compatibility.Type.AllowAny) || compatibility.getType().equals(Compatibility.Type.DenyAll);
                if (! isCompatibilityValid) {
                       log.error("Invalid compatibility type for  serializationFormat {}, only Allow Any or Deny All is possible for this format");
                }
               return  isCompatibilityValid;
...

Suggestions for an improvement
