Provide a way to sanitize the generated name of a physical resource

Registered by Mathieu Velten on 2016-09-05

In our infra the Nova name is used as the registered hostname in our DNS. Since hostnames don't support underscore and we want coherency between the Nova name and the hostname to avoid confusing the user, Nova has been patched to reject request with _ at the API level.
However in Heat resource names like the server name are derived from the stack name and the heat resource name, which can include _.
My proposition is to add a configurable element (resource_name_strip_regex for example) that allow to specify a regex to filter the name. Any piece of the name matching the regex would be removed.
