Clean up signalling events after stack updates

We provide an Event object to every stack update in order to signal it that
we need to cancel the update; this change ensures that we delete it when
the thread is complete. Previously we were leaking memory on every update.

Update references to auth_token middleware

There's references to the auth_token middleware in keystoncelient.
The auth_token middleware has been moved to keystonemiddleware and
the version in keystoneclient shouldn't be used anymore.

If these references aren't updated, then when options are changed in
keystonemiddleware.auth_token the heat-api will fail to start because
there's duplicate options in keystoneclient.middleware.auth_token.

Make sure that the properties are stored on updates

Previously properties_data was only stored on creation, now
this is getting passed to the update mechanism too.
Later we can look at reworking this into a single mechanism.

Don't update a LoadBalancer under autoscaling control

Unfortunately, Autoscaling currently uses the update() method of a
LoadBalancer resource to do updates, with the result that the current
member list gets persisted (good) and used to compare in the event of
future *stack* updates (bad).

With this patch, we assume that LoadBalancers under the control of
Autoscaling will never have a members list property supplied in the
template.  We then ignore any updates to Autoscaling LoadBalancers that
don't actually modify the template.

The test changes revert the changes made in order to be able to merge
d32370233eaf2a5c32888f269bd1dc5e0e787467, before which LoadBalancers were
behaving correctly.
