Update Ember to v3.0.0

[Alonski]

User Story

As a developer I want to be using the latest Ember version while working on the Ember API Docs so that I can use the latest Ember features and not introduce deprecations.

As a user I want a good example of an Ember app with the latest Ember version so that I can learn how to build good Ember apps.

Description

Type:

Summary: ...
I will update Ember to v3.0.0

Expected behavior

App will be using Ember v3.0.0

Actual behavior

Currently App is using Ember v2.17.0

Reproduction

• Run Ember -v
• Look at Ember Version

Additional Information

Currently there is an issue with the project.nodeModulesPath deprecation that is problematic because a few addons that are used by this project throw this deprecation. We can't update to v3.0.0 until these addons are fixed.

So @Alonski has graciously gotten us most of the way there. What's left is to test out the current branch that his work is on (3-0-upgrade) and maybe update the rest of the way. @sivakumar-kailasam can you remember any issues outstanding that you recall? Is the project.nodeModulesPath deprecation mention above what is stopping this?
