Preventing pool deletion if pool has healthmonitor
If HM is associated to pool, HM should be deleted prior
to pool deletion.
Trying to delete pool with HM will fail with EntityInUse exception.
This is to preserve common neutron's API concept to delete cascade
resources' subresources only.

Title:
unable to delete lbaasv2 health monitor if its listener deleted
Status in neutron:
Fix Released
Bug description:
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.
