* It was necessary to add default ports for fasthttp client. After migration to the std.httpclient it's no longer needed. * An additional configuration is required at proxy servers with implicitly set 80/443 ports to the host header (such as HA proxy. It's expected that after upgrade __address_ label may change. But it should be rare case. 80/443 ports are not widely used at monitoring ecosystem. And it shouldn't have much impact.
