Voting API for Drupal8

Suppose it's great time to start discus implementation for D8

1) does 7.x-3.x branch is stable enough to start?
2) is there a reason to introduce an entity for vote?

Initial working conversion from 7.x-3.x is https://github.com/andypost/votingapi/tree/8.x-1.x

Hi. I'm sure you're probably aware of this already, but just to mention, I tried to install the D8 version and receive a fatal error:

mod_fcgid: stderr: Uncaught PHP Exception Drupal\\Component\\Plugin 17 \\Exception\\InvalidPluginDefinitionException: "The "vote" entity type did not specify a storage handler." at /Users/alan.evans/Sites/d8/core/lib/Drupal/Core/Entity/E 17 ntityManager.php line 312, referer: http://d8.local:8083/admin/modules

I'm presuming this is just because the storage is only a stub, based on the previous commit message "Add vote entity with a stub for storage. ".

A few of us are currently at the Amsterdam code sprints and we might try and submit a pull request to fix this if we can, and if that's ok with you.

More recent activity has been going on at #2379167: Drupal 8 port of Voting API, so closing this issue so that work doesn't get split between the two.
