Bug description:
  i want to display the bug as follows:
  make  sure  the role is admin:  source  devstack/openrc  admin admin
  i create a private flavor as follows：

  nova  flavor-create test1   7    512    4    2

  make  sure  the role is demo:  source  devstack/openrc  demo demo

  ok,now i use 'nova flavor-list'

  so,the demo can boot a new instance with the  private flavor.i want to prevent other tenants accessing my private flavor, such as the  command:  nova flavor-show , only on this way can we prevent the other tenants use my private flavors to create instance.

  ok,i modfiy the codes in 'nova/api/openstack/compute/flavors.py' to fix this bug.
  def show(self, req, id):
      """Return data about the given flavor id."""
      try:

       context = req.environ['nova.context'] 
       flavor = instance_types.get_instance_type_by_flavor_id(id, context)

      
       if not context.is_admin:
           flavors = self._get_flavors(req)
           flavor_is_not = False
          for k in flavors:
              if k.get('flavorid', None) != flavor.get('flavorid', None)\
                                 and flavor.get('is_public', None) == False:
                  flavor_is_not = True
          if flavor_is_not:
              raise webob.exc.HTTPNotFound()
      req.cache_db_flavor(flavor)
      except exception.NotFound:
          raise webob.exc.HTTPNotFound()

      return self._view_builder.show(req, flavor)
