Customize Chilli DHCP Leases

[edospadoni]

In very large environments chilli daemon DHCP refuse to dish out more than 512 leases, we can see in the logs this message:

reached max connections 512!

The DHCP of chilli daemon by default manages until 512 IP addresses, but luckily this value can be customized via the variable maxclients.

Proposed solution

Handle the new varibile through a new config prop called Maxclients that overrides the chilli conf.
