[FEATURE ember-contextual-components] dot-path

[mixonic]

Consider paths with dots in them for rendering as a component. References https://github.com/emberjs/rfcs/blob/master/text/0064-contextual-component-lookup.md

For example via the range hook and redirection:

{{#with (hash profile=(component "user-profile")) as |userComponents|}}
  {{userComponents.profile}}
{{/with}}

And via the inline hook and redirection:

{{#with (hash profile=(component "user-profile")) as |userComponents|}}
  {{userComponents.profile some=attrThing}}
{{/with}}
