refs https://github.com/TryGhost/Ghost/issues/9623 - add `oembed-parser` module for checking provider availability for a url and fetching data from the provider - require it in the `overrides.js` file before the general Promise override so that the `promise-wrt` sub-dependency doesn't attempt to extend the Bluebird promise implementation - add `/oembed` authenticated endpoint - takes `?url=` query parameter to match against known providers - adds safeguard against oembed-parser's providers list not recognising http+https and www+non-www - responds with `ValidationError` if no provider is found - responds with oembed response from matched provider's oembed endpoint if match is found
