Public bug reported:
problem is in Kilo neutron-lbaas branch.
monitor is attached a pool.
When pool and listener were deleted, not error reported that there is a
health-monitor associated to pool.
If all lbaas resoruces except health-monitor were deleted, health
monitor can not be deleted.
See the following procedure to reproduce this issue:
$ neutron lbaas-loadbalancer-create --name=v-lb2 lb2-v-1574810802
$ neutron lbaas-listener-create --protocol=HTTP --protocol-port=80
--name=v-lb2-1 --loadbalancer=v-lb2
$ neutron lbaas-pool-create --lb-algorithm=ROUND_ROBIN --protocol=HTTP
--name=v-lb2-pool --listener=v-lb2-1
$ neutron lbaas-member-create --subnet lb2-v-1574810802 --address 10.199.88.3
--protocol-port=80 v-lb2-pool
$ neutron lbaas-member-create --subnet lb2-v-1574810802 --address 10.199.88.4
--protocol-port=80 v-lb2-pool
$ neutron lbaas-healthmonitor-create --max-retries=3 --delay=3 --timeout=10
--type=HTTP --pool=v-lb2-pool
$ neutron lbaas-member-delete 4d2977fc-5600-4dbf-8af2-35c017c8f4a0 v-lb2-pool
$ neutron lbaas-member-delete 2f60a49b-add1-43d6-97d8-4e53a925b25f v-lb2-pool
$ neutron lbaas-pool-delete v-lb2-pool
$ neutron lbaas-listener-delete v-lb2-1
$ neutron lbaashealthmonitor-delete 044f98a5-755d-498d-a38e-18eb8ca13884
neutron log seems point to lbaas resources were gone.
In this specific issue, we should just remove the health monitor from system.
