REST API Meta Support

Automatically stores the meta data from the meta field of a wordpress REST API posts (/wp-json/wp/v2/posts) or pages (/wp-json/wp/v2/pages) POST in the meta data associated with the created page or post using update_post_meta. The key / value information sent in the REST POST ‘meta’ object field is stored as both ‘key’ and ‘_key’ to support different plugin formats.
For example, if trying to set the YOAST SEO Plugin values dynamically when creating a page from the REST API, you would simply add the fields to the meta field of the REST POST data when you POST the endpoint, and the plugin values will be added to the page:

{
...
  'meta': {
    'yoast_wpseo_title': "Title set from REST call"
    'yoast_wpseo_metadesc': "Meta description set from REST call"…
