Bug 1889272

These features are now implemented in test_server.go

> URL query string parameters to support:
> 1) respond_with_request_headers - server should send back all received GET
> request header in response body.

the /request endpoint replies with a content that includes the provided headers:

$ curl -H "Foo: bar" http://127.0.0.1:8080/request   
GET /request HTTP/1.1
Host: 127.0.0.1:8080
User-Agent: curl/7.76.1
Accept: */*
Foo: bar

1


> 2) delay_response - delay the response with a value set as parameter (to
> simulate busy server, hatcheck response id delayed)

the /delay endpoint implements it:

$ time curl http://127.0.0.1:8080/slow\?delay\=4s
1curl http://127.0.0.1:8080/slow\?delay\=4s  0.00s user 0.00s system 0% cpu 4.011 total


> 3) response_with_status_code - response with the status code set as
> parameter 

The /request endpoint can take a "response_code" parameter and reply with the desired response_code

$ curl -v http://127.0.0.1:8080/request\?response_code\=402
