Deprecate accordions

[anselmbradford]

Based on recent discussion, single expandables should be deprecated and all expandables should appear inside an expandable-group, even if it's one item. o-expandable likely would be deprecated, and o-expandable-group_item or similar added.

Current behavior

• Expandables and expandable groups are separate organisms, but are delivered inter-twined.

Expected behavior

• Since expandables and expandabled groups are delivered together, they should be fully merged as one organism.

Proposals going forward:

• Expandable.js is turned into a group and no expandable ever appears outside of a group, even if there is only one. Vote 🎉 :

• Expandable.js is broken into ExpandableGroup.js and Expandable.js. ExpandableGroup.js handles accordion behavior. Expandable groups and single expandables may both exist. Vote ❤️

• Expandable.js has accordion behavior removed and expandable groups disappear. Vote 👍

@cfpb/cfgov-frontends Please vote on one (or if you have a radical 🍣 throw that into the mix and screw up this whole process. Add your vote as an emoji reaction to this comment.

Per chat, going forward I will be pursuing the second option, both ExpandableGroup.js and Expandable.js, and if accordion behavior can be removed, we'll remove ExpandableGroup.js.

Stories of Accordion's death are greatly exaggerated, tis alive and well and in use at https://www.consumerfinance.gov/owning-a-home/closing-disclosure/. I've fixed the existing bug in cf-expandables and have the updates working in cfpb/consumerfinance.gov#4365
