Maciej Józefczyk ab32d7ae64 [OVN] Allow IP allocation with different segments for OVN service ports 
OVN creates localport [1] for each network that has metadata
and allocate IP address from subnet within this network that has
DHCP enabled. The traffic from this port will never go outside
the chassis.

While using multiple segments with subnet linked to each segment
OVN needs to create an allocation of IP address for each of those
subnets [2] in order to generate data for OVN NBDB IPv4 DHCP Options.

The change [3] started to validate that condition, while multiple
IP addresses from different segments are tried to be allocated on
one port. We can skip this for OVN Metadata port, because there
is no reason to prevent those kind of allocation for OVN.

For stable branches we decide if a port is distributed or not
by looking for DEVICE_OWNER_DHCP device owner  and `ovn` device_id,
instead DEVICE_OWNER_DISTRIBUTED device owner.
