There are two changes here, and some caveats/commentary:
1. The “State“ table column was actually sorting only by status. The state was not an actual property, just something calculated in each client row, as a product of status, isEligible, and isDraining. This PR adds isDraining as a component of compositeState so it can be used for sorting.
2. The Sortable mixin declares dependent keys that cause the sort to be live-updating, but only if the members of the array change, such as if a new client is added, but not if any of the sortable properties change. This PR adds a SortableFactory function that generates a mixin whose listSorted computed property includes dependent keys for the sortable properties, so the table will live-update if any of the sortable properties change, not just the array members. There’s a warning if you use SortableFactory without dependent keys and via the original Sortable interface, so we can eventually migrate away from it.
As the angle bracket invocation RFC says:
> There is no dedicated syntax for passing an "else" block
> directly. If needed, that can be passed using the named
> blocks syntax.

Unfortunately, using a contextual component doesn’t help as
the yield inside that component will still result in content
rendering that would show when the source isn’t empty. So
we decided to change the interface so you have to check
whether the source is empty before using it, which aligns with
how list-table works.
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.
