Better service support in JDL

[agoncal]

At the moment we can generate a service or not with a single line in the JDL :

service Proposal with serviceClass

It would be good to be able to add method signature to generate methods. With a simple grammar and focusing on defaults.

service Proposal with serviceClass {
  method1(String),                   // public void method1(String param1)
  method2(String s),                 // public void method2(String s)
  String method3(Integer, Integer),  // public String method3(Integer param1, Integer param2)
  private MyEntity method4(Integer)  // private MyEntity method4(Integer param1)
}

This would create the same methods as today (save, findAll, findOne, delete) as well as creating the demanded methods.

@agoncal for this to happen, the generator must be updated (templates, JS files) to accept this kind of input. As for the JDL (parsing, exporting, etc.), it would be quite easy to do.
@jdubois what do you think?

I think it would better be discussed together with jhipster/generator-jhipster#6275.
