feat(server): add HTTP/1 header read timeout option (#2675)

Browse Source 
Adds `Server::http1_header_read_timeout(Duration)`. Setting a duration will determine how long a client has to finish sending all the request headers before trigger a timeout test. This can help reduce resource usage when bad actors open connections without sending full requests.

Closes #2457
