connection timeout.

-CWMP_KEEP_ALIVE_TIMEOUT
-  How long (in milliseconds) to maintain an open TCP connection while waiting
-  for the CPE to send the next HTTP request. If a CPE takes longer to respond
-  the server will terminate the TCP connection and store the session details
-  temporarily in the DB cache. This results in a performance hit. Adjust this
-  for better performance if your devices often take longer than 5 seconds to
-  respond.
