Add support for configurable arp timers in L3 mode

L3 mode supports two timers:
- arp_update_time, defaulted to 1 second, which makes PROX to send
  arp request every second for active flows
- arp_timeout, previously defaulted to 30 seconds, which makes PROX
  consider a MAC address as invalid if no arp_reply was received
  within those 30 seconds.

Those timers values were hardcoded. They can now be configured through
the configuration file (within the core section), using resp.
"arp update time" and "arp timeout" keywords. Unit is milli seconds.
The default becomes respectively 1 second and 2 weeks.
