[OVN] Disable the mcast_flood_reports option for LSPs
The mcast_flood_reports option was being enabled on LSPs as a workaround
for a problem in core OVN. The issue in core OVN has been fixed and this
workaround is now causing an increase in the number of actions on the
table 38 of OVN (at the risk of hitting a size limit).
This patch disables the mcast_flood_reports option on newer versions of
OVN while keeping the backward compatibility with the old ones.
Since the fix in core OVN does not expose any information to the CMS to
tell us that the issue is fixed this patch uses the NB DB schema version
to determine if this is an old or a new OVN version.
