[Bug 1907306] [NEW] networkd dhcpv4 client never attempts more than 2 renew and 2 rebind

[Dan Streetman]

Public bug reported:

[impact]

networkd dhcpv4 client never attempts more than 2 renew and 2 rebind

[test case]

configure an interface to use dhcpv4; acquire a dhcpv4 address, then
stop the dhcpv4 server, and wait for the networkd client to perform its
renewals and rebinds before expiring the lease

[regression potential]

any regression would likely result in problems receiving and/or
maintaining a dhcpv4 address

[scope]

this is in progress upstream, and would need to be applied to all
releases
