feat(kuma-cp) server for managing provided ca

Summary

Server for managing Provided CA.

Open questions

1. Name
   How do we name common server for Dataplane Token Server and CA Manager Server? For now I introduced name "Admin Server".
   Because of the lack of the name I did not introduce new configs for now and just hardcoded the port.
   Maybe after all it's easier to have a separate server?

2. Error Handling
   For now I just used functions from api-server package, but it's a bit weird to have dependency inside ca/provided/rest on that. Should we extract error handler and error types to something like core/rest/errors?

If I understand correctly, the requirement is to have a single server.

Should we extract error handler and error types to something like core/rest/errors?

Makes sense 👍

Merged two servers together and provided autoconfig with migration form old one.

Looks like a swallowed error

good catch!

Name dataplaneTokenWs that will appear in YAML and env variables is too implementation-specific.

Let's use the same approach as in Catalog.

E.g.,

type AdminServerConfig struct {
   Apis *ApisConfg
}

type ApisConfig struct {
  DataplaneToken *DataplaneTokenApiConfig
}

type DataplaneTokenApiConfig struct {}
