Bug description:
  [Impact]

  There are 500 error when creating
  AodhGnocchiAggregationByResourcesAlarm

  If openstack env has the same projects name ( e.g. services ) in
  different domain ( e.g. default, service_domain), It will get default
  domain even if you want to choose service_domain.

  This is affected to O, P, Q and Bionic ( but Ocata backporting is in
  progress, there is testing error so I didn't put it here )

  [TestCase]

  1. deploy openstack env (https://pastebin.ubuntu.com/p/3SXDQT9hWq/)
  - juju run-action heat/0 domain-setup

  2. create new domain, project, user, role etc (https://pastebin.ubuntu.com/p/x8VDrzbWS3/)
  3. create image, flavor, network if needed
  4. source testrc (https://pastebin.ubuntu.com/p/b25bSY3ktf/)
  5. openstack keypair create testkey > ~/testkey.pem; chmod 600 ~/testkey.pem;
  6. prepare stack templates
  web.yaml(https://pastebin.ubuntu.com/p/vr6brGjqbp/)
  lb_server.yaml(https://pastebin.ubuntu.com/p/mmJ39VsCg6/)
  7. adjust configuration
  - gnocchi_external_project_owner = services below [api] on aodh.conf
  gnocchi_external_domain_name = service_domain
  - insert belows on credentials
  project_domain_name = service_domain
  user_domain_name = service_domain
  8. openstack stack create -t ./web.yaml asg --wait

  [Regression]
  This patch changes aodh code for gnocchi resource. this patch adds new option for gnocchi resource setting, User should set this properly. After this patch, restarting aodh(apache2) services. this causes short service unavailable.
