Add a useTags flag to allow tags to be used to generate interface / controller classnames

[eamon316]

Description

Currently SpringCodegen uses the basePath to generate classname for interface / controller.

I would like to be able to use tags to control the generated classnames (this appears to be the pattern for most other generators).

Just wondering if there is any particular issue why the SpringCodegen uses basePath and if there are any known issues with using tags?

Warning : if an operation has 2 tags then you get 2 mappings for the same path which will fail.
I think some generators (JAX-RS?) use only the first tag of the operation.

I did quick test. If there are 2 tags the first one is used.
e.g.

tags:
    - Tag1
    - Tag2

you get Tag1Api.java and Tag1ApiController.java
