[REQ] [SPRING] add a config to exclude swagger import

[blackdev1l]

Is your feature request related to a problem? Please describe.

Hi everyone, i noticed that you can't generate a spring code without all the swagger annotation and import io.swagger.annotations.*; i would love to have an option to opt out all the unnecessary annotations and import from the generated code.

Describe the solution you'd like

I would have the same configuration useSwaggerAnnotations used in jax-rs generator in the spring generator,

Describe alternatives you've considered

I didn't think to any alternative, the configuration defaulted to the standard behavior could be the right choice

I could work on it if this proposal will be accepted!

Thanks
Cristian
