After a successful start up allow an interceptor to be called

On start-up some other systems need to be notified that the start-up was successful.
This is a request to allow an interceptor to be defined in the standalone*.xml file that could be called on a successful start-up.
If the startup was unsuccessful ie had any errors the interceptor would not be called.

Whether the startup is successful can be found out by the following cli command

/core-service=management:read-boot-errors

So the information on whether to call the interceptor or not is already known.
