[Proposal] Overriding/Setting the service name for a specific contribution

[gpolaert]

Currently the default service name is supported by the tracer.
PR: #64

The user can set the default service:

• Using the YAML file (default-service-name props)
• Building a new instance of the DDTracer new DDTracer("service-name", ...)

Goal

We want to allow a third way for the user to change the service name at the contribution level. For instance rename mongoto my-app-mongoservice when using the mongo contrib provided.

Proposal

At the point, we have the notion of decorators. But this concept should rest private from the user perspective. So, we will a simple API to allow the user to rename an existing service name to another.

tracer.addRule(Rules.SERVICENAME, new MappingRule("mongo","my-app-mongo"))

rules:
  service-name:
    - mapping: ["mongo", "my-app-mongo"]
    - mapping: ["jdbc", "my-app-jdbc"]

Has anyone taken a look at this? This would be nice to have.

@tseruga it is still on our radar, but we haven't finalized how we want to do it. Thanks for the feedback though!
