* reverseproxy: Begin refactor to enable dynamic upstreams Streamed here: https://www.youtube.com/watch?v=hj7yzXb11jU * Implement SRV and A/AAA upstream sources Also get upstreams at every retry loop iteration instead of just once before the loop. See #4442. * Minor tweaks from review * Limit size of upstreams caches * Add doc notes deprecating LookupSRV * Provision dynamic upstreams Still WIP, preparing to preserve health checker functionality * Rejigger health checks Move active health check results into handler-specific Upstreams. Improve documentation regarding health checks and upstreams. * Deprecation notice * Add Caddyfile support, use `caddy.Duration` * Interface guards * Implement custom resolvers, add resolvers to http transport Caddyfile * SRV: fix Caddyfile `name` inline arg, remove proto condition * Use pointer receiver * Add debug logs Co-authored-by: Francis Lavoie <lavofr@gmail.com>
