    FIX OVN LB Health Monitor checks for IPv6 members
    
    After [1] the IPv6 backend members health checks are supported,
    they are mapping into field ip_port_mappings of the OVN LB entity
    and translated to OVN SB DB Service_Monitor entries, same way
    for IPv4 ones.
    
    However, IPv6 backend members require being enclosed in [ ], and
    this was not occurring, causing it not to translate into entries
    in the Service_Monitor table. This patch fixes this issue.
    
    Furthermore, a one-time maintenance task has been developed to fix
    those existing IPv6 Health Monitors directly upon the startup of
    the ovn-octavia-provider component without requiring any action
    by the administrator/user.

Title:
  [ovn-octavia-provider] OVN LB health checks for IPv6 not working

Status in neutron:
  Fix Released

Bug description:
  When creating a health monitor for a IPv6 load-balancer the members
  are not correctly checked. Upon further analysis, the problem is
  related to there being no entry in the OVN SB database
  (Service_Monitor table) to map LB health checks created in the OVN NB
  database.
