Description

add a way to check upstreams via http request

defined a endpoint on my host /healthy which returns ok on success currently i used haproxy but i want switch to caddy

example config in http health check:

"active": {
			"port": 0,
			"interval": 0,
			"timeout": 0,
			
			// new fields
			"type": "http",
			"host": "my-host.com",
                        "path": "/health",
                        "expect_status": 200,
			
		},

Contributor guide

Research direction
Implement HTTP health check for active upstream health checks. Extend the existing health check configuration to support 'type': 'http', 'host', 'path', and 'expect status' fields. Parse these in the config and perform HTTP requests instead of TCP connect. Handle response status code matching. Update tests and documentation.
