Streamline the Hazelcast support with boot 1.3 and support storing events in hazelcast

closes #113

Due to our use of @Conditionals on our @Configuration-classes the import must be deferred, so that the classes are processed after all other @Configuration-classes

By using local.server.port, local.managment.port and ApplicationReadyEvent the port detection and ready state detection can be simplyfied in boot 1.3

But make no use of it.

closes #88

There is currently a problem if the Admin Client has version 1.2.0 and the Admin Server has version 1.2.1 due to changes to the model. The server is able to handle the old format but the client is not able to handle the new Format. To prevent this problem in future the response is not deserialized. Only the needed inforamtion (the id) is exctracted.
