Previously we used a `shouldReconcile` method in order to decide whether
a response should trigger a reconciliation of the frontend ember-data
'source of truth' or not. It's a lot nicer/clearer if this 'flag' can be set
alongside the HTTP request information, moreover we almost have the same
functionality in `If-Range`/`Partial Content` HTTP functionality.
Here we partly follow this HTTP semantics but use a custom `X-Range` header
instead.
* Add uri identifiers to all data source things and make them the same
1. Add uri identitifer to data-source service
2. Make <EventSource /> and <DataSource /> as close as possible
3. Add extra `.closed` method to get a list of inactive/closed/closing
data-sources from elsewhere
* Make the connections cleanup the least worst connection when required
* Pass the uri/request id through all the things
* Better user erroring
* Make event sources close on error
* Allow <DataLoader /> data slot to be configurable
* Allow the <DataWriter /> removed state to be configurable
* Don't error if meta is undefined
* Stitch together all the repositories into the data-source/sink
* Use data.source over repositories
* Add missing <EventSource /> components
* Fix up the views/templates
* Disable all the old route based blocking query things
* We still need the repo for the mixin for the moment
* Don't default to default, default != ''
* Add model layer support for filtering intentions by service
* Add Route, Controller and template for services.show.intentions tab
We are still loading the intentions themselves in the parent Route for
the moment
* Load the intentions in in the parent route for the moment
* Temporarily add support for returning to history -1
Once we have an intention form underneath the service/intention tab this
will no longer be needed
* Add the new tab and enable blocking queries for it
* Add some further acceptance testing around intention listings
Repositories are a class of services to help with CRUD actions, most of
the functionality is reused across various Models. This creates a new
repository service that centralizes all this reused functionality.
Inheritance via ember `Service.extend` is used as opposed to
decorating via Mixins.
1. Move all repository services (and their tests) to a
services/repository folder
2. Standardize on a singular name format 'node vs nodes'
3. Create a new 'repository' service to centralize functionality. This
should be extended by 'repository' services
