Research and refactor component to leverage this.attrs

[notmessenger]

This is against the addon/mixins/component.js file, as well as the sl-able and sl-unable components.

This issue involves more than just simply replacing syntax, but instead requires understanding what this new capability offers and determine what parts of the component implementation should/needs to be modified to align. softlayer/sl-ember-components#617 contains resources related to this.attr research.

See the notes on softlayer/sl-ember-components#617 as to why work on this issue has been postponed.
