Added variable ``keepalived_sysctl_tcp_retries`` that allows to control
number of retries kernel will make to give up on connection. It controls
net.ipv4.tcp_retries2 sysctl setting which default value of which is 15.
Default value of ``keepalived_sysctl_tcp_retries`` is 8, so VIP failover
time will be ~1min. Setting ``keepalived_sysctl_tcp_retries`` to 0 will
remove mentioned sysctl setting.
