Support for OpenAPI servers field

[AllieJonsson]

What are the steps to reproduce this issue?

Generate from Lichess api spec

What happens?

There is no way to know what endpoint to use, as the spec has different endpoints for many api calls, specified by the servers field.

What were you expecting to happen?

A way to use the servers field.

Any logs, error output, etc?

Any other comments?

Unsure how this best would be handled? Maybe let there be an optional parameter to be sent to the function doing the api call, which could be the servers data?
