odhcpd: add option for setting preferred lifetime
"valid_lft" and "preferred_lft" are different. If the "preferred_lft"
is expired the prefix should be avoided in source prefix selection.
However, the interface is allowed to still receive downstream traffic.
preferred_lfetime:
Limit for preferred lifetime of a prefix
If you want the old behavior, you have to set preferred_lifetime to
the same value as leasetime.
