Title:
  heat stack delete fails when token expires

Status in OpenStack Dashboard (Horizon):
  Invalid

Bug description:
  If i create a heat stack and happen to delete the stack at a time when
  the keystone token is expiring the heat stack delete fails.  I
  originally found this when deleting a very large heat stack, but you
  can repo it by changing your keystone expiration to 300 seconds.

  
  1. create a stack with 5 servers and some volumes
  2. change the keystone.conf and restart keystone service
      change to 5 minutes
  [token]
  expiration = 300

  3. log on Horizon and wait to the 4th minute and then
      trigger stack-delete from horizon.

  4 stack-delete failed, detailed logs are as attached:

  This time it's deleting nova server error. So this problem is not cinder specific, should be a problem with other resources as well.
