T5222: reverse-proxy add send-proxy option for backend server
To accept a Proxy Protocol header on incoming TCP connections,
add an accept-proxy parameter to the bind line in a frontend section.
This parameter detects both Proxy Protocol version 1 (text format)
and Proxy Protocol version 2 (binary format).
