Neither fdb_removal_limit nor mac_binding_removal_limit config
options currently get set in the OVN DB. This patch corrects that
and adds missing testing for the MAC_Binding aging maintenance
task.
Fixes: 0a554b4f29 ("Add support for OVN MAC_Binding aging")
Fixes: 1e9f50c736 ("Add support for FDB aging")
