Document mocks and fixtures by node server

[villander]

In the old site, we had a section about the creation of node servers

Old site - https://ember-cli.com/user-guide/#mocks-and-fixtures
Ember CLI blueprint - https://github.com/ember-cli/ember-cli/tree/master/blueprints/http-mock/files/server/mocks

We have a good example of the usage here on ESA addon - https://github.com/simplabs/ember-simple-auth/tree/master/packages/test-app/server

If someone wants to pick up this issue, that would be great!

To-do:

• Read over the old site content
• Figure out where this information should go in these CLI Guides
• Copy over the old information
• Make any updates you think are needed

@villander Your "old site" link redirects to the normal CLI guides, unless I'm missing something here. Theres nothing about mocks or fixtures on that page.

[villander]

There's nothing because the "old site" is redirecting to the new site. But it was there.

You need to find some way to check the "old site" codebase to be able to pick this information @esquith

@villander Thanks! My apologies.

Maybe the same as #188
