Sugaring dynamics in ShadowDOM

[sjmiles]

Polymer sugaring, including event processing, data binding, and node marshalling, only happens once at shadow DOM creation time.

As there may be use cases where users want to update/replace shadow DOM and still have sugaring, we probably should provide an API for doing this imperatively.

Here is an example of some code that could be used, in particular, for managing MDV bindings on shadow DOM replacement.

This is now pretty easily done by just making a template and calling instanceTemplate:

This is pretty flexible and seems like it doesn't need much improvement. The only thing missing in this case is node marshaling (which can be manually addressed by calling marshalNodeReferences(root)). Since that issue is separately addressed, closing this issue.
