    [5596] renew-timer and rebind-timer now optional for DHCPv4 · dec8d15f
    Thomas Markwalder authored
    v4 Parsing now allows renew/rebind timers to be unspecified,
    and kea-dhcp4 logic now matchs ISC DHCP:
    
    1. Send T2 only if it is specified and is less than lease lifetime
    2. Send T1 only if it is specified and is less than either T2
    if specified, or lease lifetime in the absence of T2
    
    doc/guide/dhcp4-srv.xml
        Updated discussion of rebind/renew-timers
    
    src/bin/dhcp4/dhcp4_srv.cc
        Dhcpv4Srv::assignLease() - modified to sanity check
        T1 and T2

        updated numerous tests
    
    src/lib/dhcpsrv/network.cc
        Network::toElement() - only outputs T1, T2, and
        valid lifetime if they are specified
    
    src/lib/dhcpsrv/network.h
        Network() - inits t1_, t2_, and valid_ to unspecified
        Triplet value
    
    src/lib/dhcpsrv/parsers/dhcp_parsers.cc
        Subnet4ConfigParser::initSubnet() - allow renew-timer and
        rebind-timer to be optional
    
    src/lib/dhcpsrv/parsers/simple_parser4.cc
        SimpleDefaults SimpleParser4::GLOBAL4_DEFAULTS - removed
        entries for renew-timer and rebind-timer
