Kernel enforces that all nexthops must be reachable through a route.
L3Cfg is generating dependent onlink routes to solve this problem but
the IPv4 ECMP commit is happening before that.
To solve this we introduce two boolean fields "is_new" and "is_ready" to
know in which state is the L3Cfg affected. Initially, "is_new" is TRUE
and "is_ready" is FALSE. Here we schedule a commit on idle and we set
"is_new" to FALSE. When revisiting, we set "is_ready" to TRUE and then
we set the ECMP IPv4 routes.
When a reapply kicks in we reset the L3Cfg state by setting "is_new" to
TRUE.
