Add heartbeat support (stop all cores in case of TCP socket issues)

"heartbeat timeout" (in second) can be specified as a global parameter
in PROX config file. If set, a timer is started when the first
command is received from the TCP socket. This timer is reset at each
commands received through the TCP socket. If the timer expires, then
- all cores are stopped
- the TCP socket is closed, causing an error at client side.

This feature helps in case a script starts PROX and the traffic generated
through PROX causes issues to the control plane.
