The patch introduces a new config section ovn_nb_global. All options
from this section are passed to OVN Northbound NB_Global table to
configure Northbound OVN.
First option is ignore_lsp_down to override OVN default configuration.
This option was changed in OVN to `true` [1] but for Neutron it's better
to not answer ARP packets when ports are in DOWN status.
