Support for security schemes

[davidgayoso]

Currently, the plugin is not able to generate authorization / security schemes on the generated endpoints. We are using the plugin on our project and we would like the plugin to generate something that would allow us to work with Bearer tokens.

Here you have a link to the Swagger documentation that shows what I am talking about: https://swagger.io/docs/specification/authentication/bearer-authentication/

This feature is quite urgent, so it would be greatly appreciated to have it working as soon as possible.
