optional dependencies and Server loadings

[fiorenzino]

we could evaluate in config file to initialize in Server class:

• config file

I'm thinking about:

• for "cookies and session" (if we have "cookies": true in config)
• db client (if we have url or driver_class or db_driver in config)
• swagger ("swagger": true in config )

What do you think about?

[FroMage]

I agree, but I'd keep the current defaults, so the config would be useful to disable them.

Should it continue to be referenced as Swagger or OpenAPI?
