Comment 10 for bug 1365727

@Kyle- The primary purpose of this patch was to enforce network profiles (effectively segmentation ranges) being scoped per-tenant. Without this patch (or with the config value set to false) they are effectively global. Unlike what the commit message says, there is no modification of other tenant's network profiles possible, as that is locked to admin-only at the CLI level. The only action possible with a profile that isn't assigned to a tenant is network creation, in which case the behavior is no different then default Openstack behavior- all of the configured segmenation range is available to all tenants.

I have updated the bug title/description. Since this is a backport I can't modify the original commit message.
