Provide network layer informational access in the OFTP session
In the OFTP session some access to the network layer info is desired (i.e Listening IP of the server, listening port of the server, IP address of the client, If connection was made over TLS/SSL, TLS/SSL client certificate if any,...)
Those informations can be useful to decide if client match security requirements and accept or refuse the OFTP session (SSL required for partners that don't send encrypted files for example), or doing some throttling (OFTP client connecting/reconnecting too fast, ...)
