[LBaaS V2] A delete operation on healthmonitor throws HTTP 500 Internal Server Error

[German Eichberger]

I attempted to delete a healthmonitor object using the CLI and the call failed with an HTTP 500.Subsequently I deleted the pool and the loadbalancer objects before successfully being able to delete the healthmonitor.

Not sure if there is a dependency ,but the way to handle this gracefully is to report the error and not throw the HTTP 500 .

In juno, for the above mentioned scenario the following error is thrown,

root@controller:~# neutron lb-healthmonitor-delete 4e95202d-4913-4ac2-91b8-cf8683da95c7
Health monitor 4e95202d-4913-4ac2-91b8-cf8683da95c7 still has associations with pools (HTTP 409) (Request-ID: req-bb9db640-e6fe-48c7-8a04-a95534a52099)

This is expected output.

Could you please confirm if this error is simulated in juno.

If so, can you attach the following logs/info?

1. output of command,
neutron --verbose lb-healthmonitor-delete <health moniotor id>

2. Neutron's
