create openstack/grian-ui git repo

grian is the irish word for sun
The grian-ui repo will host a new horizon
plugin to "enlighten" the dashboard with metrics.

This will be an offical deliverable of the Telemetry
team. While an inital prototype exists the repo
will be started from scratch so there is no upstream
repo to import.

This was discussed with both the horizon and telemetry
teams during the recent ptg.
