Carbon: Design for data tree variation of the accordion

[designertyler]

Rocket previously used an accordion as a type of data tree navigation. The v10 accordion moved the arrows to the right side which makes it more difficult to navigate and use as a data tree.

This issue is to design a way to navigate similar to a typical data tree.

the primary use case would likely be for displaying any sort of hierarchical organization

we could likely include things like searching/filtering and selection for parts of the tree as well

Thank you for looking into adding a tree component. This would be very useful for us.
Here is an additional requirement that would be awesome if could be added to this new component:
Ability to edit the tree structure

1. move nodes (folders/leaves) around
2. add/delete/rename nodes

The Sun Web Application Design guidelines have a section on Tree Details: https://pages.github.ibm.com/CloudIntegrationDesign/sun-guidelines/05-navigation.html#5.4

We have a fairly basic tree-view built out in WCE addons: https://github.ibm.com/peretz/carbon-addons-wce/tree/master/src/tree-view

Reopening given I see multiple people asking in this area recently.

This would be good addition

My product (Maximo) also requires this, although not strictly a tree view. It really is an accordion inside of an accordion. The accordion allows us to place the components we need at each level (not just text), but also have the entire tree collapsed on page-load.

^ Feel free to add comments with desired UX/visual to #4768. As #4768 states, nested accordion is not supported in design level, and discussion with our designer will be needed to see if there is a use case we need to accommodate around nested accordion and guidance on how to solve the problem area.
