Can I configure the Preferred lifetime?

[dedeckeh]

Implementation has been changed so that the preferred and valid lifetime can be configured via the DHCP leasetime uci parameter (https://git.openwrt.org/?p=project/odhcpd.git;a=commit;h=6db312a698e920ff61505ef1f42469880829774d). Unless infinite is specified as leasetime value the preferred/valid lifetimes won't have infinite anymore as value
