Bug description:
  Description
  ===========
  When an instance encounters a HypervisorUnavailable error, the non-admin user gets the info of the compute host fqdn in the error message. 

  Steps to reproduce
  ==================
  1. Spin up an instance with non-admin user credentials
  2. To reproduce the error, stop the libvirtd service on the compute host containing instance
  3. Delete the instance
  4. Deletion fails providing HypervisorUnavailable error

  Expected result
  ===============
  Error does not show compute host fqdn to a non-admin user

  Actual result
  =============
  #spin up an instance
