RabbitMQ should use net_ticktime

Browse Source 
We no longer need to force low-level TCP timeouts for dead client
detection, but should continue tuning the timeout for dead peer
detection between cluster nodes.  Using the erlang net_ticktime option
is preferrable here.

A new parameter, RabbitNetTickTime, allows tuning the Erlang
net_ticktime parameter for rabbitmq-server. The default value is
15 seconds. This replaces previous tunings in the RabbitMQ
environment file which set socket options forcing
TCP_USER_TIMEOUT to 15 seconds.
