WP REST API Integration

[MattGeri]

• Adds new REST class for WP REST API support
• Adds tests for different methods

This leaves the old REST implementation intact. The new endpoint configuration is called "REST Push Client (New)"

@philipjohn The only piece that is missing here is the actual authentication layer. On my local, I used https://wp-oauth.com/ but the actual WordPress.com implementation will be different. In the configuration, it lets you paste the Auth token for now if you want to test.

Mentioning #116 which this PR deals with.

Some feedback on this;

• When creating a "REST Push Client" endpoint, the text "To generate the following information automatically please visit the settings page" includes a broken link, and the actual Syndication settings page contains no instructions on how to set that up.
• "REST Push Client" is the WordPress.com REST service, but that isn't clear, which adds to the confusion.
• There are two REST Push clients, with different options and it's again unclear what each is and whether they should be used.
• Did you look into the "XML Pull" service which is no longer present in the 2.1 branch?
• Have you looked at migration given the identifiers for the endpoints has changed in the 2.1 branch?

Hi @philipjohn

I'll need your direction here on how to position the two different REST API push clients (one is the WP REST API and the other the WordPress.com API). Last time we spoke on Slack you mentioned there is no authentication layer setup on WordPress.com yet for the WP REST API and you were going to look at getting one setup so that we can complete the integration (and the setup process). You also mentioned we should leave the WordPress.com API intact. Let me know if you have different/new thoughts regarding this.

With regards to the XML Pull service, what specifically would you like me to look at? Does it need to be ported to version 2.1?

Thanks,
Matt
