This reverts commit 9c181604.

Currently only support soundcloud (futur providers will be add)

Use SoundCloud Oembed API https://developers.soundcloud.com/docs/api/reference#oembed in order to support more links

Currently does not support *group* embed widget (like https://soundcloud.com/groups/made-with-ableton-live)

Encapsulate spotify integration inside rocketchat:spotify package. No more inside rocketchat:oembed.

Remove rocketchat:spotify from default list of packages inside `.meteor/{packages,version}`
