Refactor controllers mapping

[efraimgentil]

The controller mapping are scaterred all over the code and packages, maybe a good time to refactor and centralize the controller mapping and path mapping handling

When when identifying the paths, we have the flux

1. PackageScanner ( identify all controllers )
2. ControllerScanner ( Find all methods with path annotations to each controller ) *
3. ControllerMapping( Interete in each method and create the hte PathMapping )
4. PathMapping ( is the map itself of the path ) **

• -> Modify the controller path
  ** -> Modify the controllerPath and the method path

And we also have the CustomPathTemplate, that adds a "/" to the start of the path string

Is not a complex logic, but maybe only the PathMapping should handle the path moddifications
