Add global security annotation

[cwansart]

Is your feature request related to a problem? Please describe.
Our API is always using authentication for all routes, so we want to use global security definition described in https://swagger.io/docs/specification/2-0/authentication/basic-authentication/

Describe the solution you'd like
I want to add
// @Security BasicAuth
somewhere central (beneath // @securityDefinitions.basic BasicAuth?)
so that

security:
  - basicAuth: []

gets added to the root resulting json/yaml file.

Describe alternatives you've considered
So far I had to add // @Security BasicAuth to every @router element.

Additional context
Not much else to show I guess.

Did you manage to get this working @cwansart ? I have a similar use case but adding the @security header beneath my @securityDefinitions.apiKey ApiKeyAuth isn't working 🤔
