This will need an options hash with id, until, description, etc

Can you also remove the entry in features.json? |

We also need to add a deprecation guide entry to the website and add a url property with the link.

So, this is kind of a fun one. From what I can tell, `ControllerContentModelAliasDeprecation` was introduced, due to Controllers having a `content` property, which `model` was aliased to. This was done because `ObjectController` and `ArrayController` were proxying controllers. But, in Ember, routes set up the `model` property of its respective controller. What this meant is that if someone declared a `content` property in their controller, `model` would—seemingly unrelated—break, hence the `ControllerContentModelAliasDeprecation` mixin. Nowadays it is fine to override `content` because the source of truth was reverse, and `model` is now the primary property, being `content` the alias. It is, then, time to remove the old deprecation and instead deprecate the alias itself, so that in the future users can define a `content` property in their controllers if they so desire. Another API bites the dust. Here's to removing yet more code in the future, and make Ember sparkle-clean.
