    Fix server metadata policy to be admin_or_owner
    
    unlock server API policy is default to admin_or_owner[1] but API
    is allowed for everyone.
    
    We can see the test trying with other project context can access the API
    - https://review.opendev.org/#/c/717182/
    
    This is because API does not pass the server project_id in policy target[2]
    and if no target is passed then, policy.py add the default targets which is
    nothing but context.project_id (allow for everyone who try to access)[3]
    
    This commit fix this policy by passing the server's project_id in policy
    target.
