Support ContentNode.options when publishing.

[kollivier]

Description

One thing we have needed in Kolibri is a way to specify rendering and other display options for particular ContentNodes. A common example of this is when HTML5 content needs to render at a particular height and/or width.

There is a PR to add this on the Kolibri side (learningequality/kolibri#6873) but we also need to be able to export those options to the SQLite db as part of the publish operation. That is what this PR does. :)

Steps to Test

• Set extra_fields to {"options": {"height": "1000px"}} on some ricecooker HTML5 kind ContentNodes
• Run ricecooker and publish the channel
• View the channel on a Kolibri with the above Kolibri PR applied and make sure the content appears at the new height!

Compatibility check

[jayoshih]

Noting that Kolibri uses a sqlite database, so not sure if this is compatible

[rtibbles]

It's using the jsonfield library JSONField which is what Kolibri uses too, so should be ok.

Nvm, just need to do a json.dumps
