OpenApi security schemes support

[evilbluebeaver]

I managed to implement an OpenApi security schemes as shown here so JWT authorization will be shown in a specific chapter and not amongst other headers.
I'm not sure if I did it right though as it needs a name for each authorization to be assigned. I decided to use constant name "JWT authorizer" as there is no difference in a presentation of the API between separate jwt authorizations after all even if one decides to use many authorization layers. As an option, it is possible to use type_name::<T> of T from JwtClaims<T> but this will lead to an inner structure leakage to the API. Maybe there are other ways but I can't come up with one.
