OVN: select a random mac_prefix if not provided
Select a random IPAM mac_prefix if it has not been provided by the user.
With this patch the admin can avoid to configure mac_prefix in order to
avoid L2 address collisions if multiple OVN deployments share the same
broadcast domain.
Remove MAC_ADDR_PREFIX definitions/occurrences since now mac_prefix is
always provided to ovn-northd
