[REQ] Improve 'spring-boot' generator to remove dependency to allow disable springfox support

Created by: ghilainm

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

Yes, i don't want to use springfox and it is automatically added to the generated classes.

Describe the solution you'd like

New option to disable springfox support if not wanted.

Describe alternatives you've considered

Post processing resources generated, or override default template, but seems like a burden which shouldn't be imposed to all spring-boot generator clients.
