feat: delete content without first doing get

[nealrichardson]

ContentItem has a delete method, but Content does not. So to delete, I have to client.content.get(guid).delete(), which is unnecessary.

Is client.content.delete(guid) the syntax you'd prefer here?

Yeah that's what I was thinking. The other solution would be if .get() deferred actually doing GET until you requested attributes that required it. That might have benefits for other resources off of the content item too (like, do I need to GET the content item in order to set an env var?), but would be a bigger change with more implications.
