Move feature from AMP Glue to Yoast SEO

[jonoalderson]

When a site is running the official AMP plugin in non-native mode, they currently also need to run our Glue plugin in order to completely synchronise their settings. We're going to remove that need by moving the last bits of features over to Yoast SEO.

• Output Twitter and FB social blocks properly.
• Prevent the AMP plugin from outputting a canonical URL tag when the post is non-public (e.g., noindex'd).

I think this can be closed, as we can't fix the problem Jono's having, see ampproject/amp-wp#4730

Is the Glue plugin otherwise now obsolete?

[jdevalk]

Yes we’re going to do an empty release for it.
