Public bug reported:
Add a configurable (opt-in) feature to terminate the Neutron agent when
Open vSwitch restarts, allowing for clean recovery through service
manager restart mechanisms.
When Open vSwitch (OVS) restarts, the current recovery process for
network services can be unreliable, leading to networking issues that
require manual intervention, in general this intervention is force
restart of agent.
Proposed change is to add two (2) new configuration options:
- OVS_TERMINATE_ON_RESTART (type: boolean, default: False)
- OVS_RESTART_EXIT_CODE (type: integer, optional)
and extend `ovs_const.OVS_RESTARTED` handling logic
(self.int_br.check_canary_table()) to trigger
`sys.exit($OVS_RESTART_EXIT_CODE)` when OVS_TERMINATE_ON_RESTART config
option is enabled.
