Rename user stories related repos

The Product Working Group has decided to cease using the term "user
stories" in favor of "development proposals" and to realign the
"userstory-dashboard" with the "featuretracker" name used for the
site where it's hosted. As a result, rename the following three Git
repositories:

  * openstack-infra/puppet-userstory_dashboard -> puppet-featuretracker

  * openstack-infra/userstory-dashboard -> featuretracker

  * openstack/openstack-user-stories -> development-proposals
