This has been a FAQ in #heat recently, so add an example showing
how you can do a list/map lookup via %index% by using a nested stack.

Adds an example showing how to get a list of all values
for an attribute of the resource in the group. Related
to a question asked on IRC recently.

Adds an example in response to a ML question, shows how you can
create a resource group containing a number of nested stacks containing
identical volumes and volume attachment resources, then pass in the
server ID to have the volumes attached to one server.
Also moves the current basic example into a resource_group subdirectory,
so we can collect related examples, and make more obvious that the
volume_with_attachment template is part of another example rather than
a standalone example template.
