There are two reasons the name property should always be set for deployment
resources:
- The name often shows up in logs, files and API calls, the default
derived name is long and unhelpful
- Sorting by name determines the merge order of os-apply-config, and the
execution order of puppet/shell scripts (note this is different to
resource dependency order) so leaving the default name results in an
undetermined order which could lead to unpredictable deployment of
configs
This change simply sets the name to the resource name, but a future change
should prepend each name with a run-parts style 2 digit prefix so that the
order is explicitly stated. Documentation for extraconfig needs to clearly
state what prefix is needed to override which merge/execution order.
For existing overcloud stacks, heat currently replaces deployment resources
when the name changes, so this change

Currently, we have a problem because the unregistration happens in the
"post deploy" phase, which works fine when the top-level stack is being
deleted, but not when the ResourceGroup of servers is being scaled down,
because then the normal "post deploy" update ordering is respected and
we try to unregister after the corresponding server has been deleted.
So, instead, register/unregister each node inside the unit of scale,
e.g the role template being scaled down, which is possible via the new
NodesExtraConfig interface, which means unregistration will take
place at the right time both on stack delete and on scale-down.
