This uses ember-page-title to add dynamic page titles throughout the
route hierarchy. When there’s more than one region, the current
current region is added before the final entry of “- Nomad”.
The draining, eligibility, and status fields now all show under a combined
state column. Draining takes precedence, then (in)eligibility; if neither of
those is true, the status displays.
This changes the templates so the element that contains
the search box is always present, instead hiding only
the box itself when there’s nothing to search. Keeping
the empty element lets it take up its flexbox space so
the facets will no longer be in the centre.
