Add ability to pass any nb_global option with the ipsec prefix to sb, which
ovs-monitor-ipsec will use to configure IPsec backend. For example

ovn-nbctl set nb_global . options:ipsec_replay-window=128
ovn-nbctl set nb_global . options:ipsec_dpd-delay=30s
ovn-nbctl set nb_global . options:ipsec_dpd-timeout=120s
ovn-nbctl set nb_global . options:ipsec_salifetime=8h

Changes since v1:
  - Make prefix string static const.
  - Fix documentation.
  - Update news entry to reference NB_Global.
