FORGE-1880 - Created command which adds annotation to class, field or method

I've just created basic command which adds annotation to the class, field or method. I'm thinking how to do the decomposition of the functionality to use it for example in `ejb-new-bean --named MyService --addNamed` command or to create `cdi-add-qualifier` command

This should be working:
```
java-add-annotation --annotation javax.inject.Named --targetClass org.app.service.MyService
java-add-annotation --annotation javax.inject.Named --targetClass org.app.service.MyService --onProperty myProp
java-add-annotation --annotation javax.inject.Named --targetClass org.app.service.MyService --onMethod myMethod
java-add-annotation --annotation javax.inject.Named --onProperty myProp
java-add-annotation --annotation javax.inject.Named --onMethod myMethod
```
