  - Merge "Create policy.json file in Ocata for non-admin user"
  - Create policy.json file in Ocata for non-admin user

    Non-admin user is not allowed to view host_status flag.
    To get the host status, policy.json file needs to be
    created as it is not available in Ocata by default.
    This is created for local and fuel installer types
    in this commit.
