This change adds missing oslo.config.opts endpoints to the config file
to generated neutron.conf, so that the following options are included
in the neutron.conf generated by the oslo-config-generator command.
1) Some options of the oslo.service library, related to periodic tasks
and base service implementation
2) Options of the oslo.reports library
3) Options of the healthcheck middleware from oslo.middleware
