Key class conflicts

[martindufort]

Looks like there is a conflict between the ndb_orm key module and the associated google.datastore.cloud key module.

Any timeline into integrating the ndb.Key functionality ?

The original key class from ndb was intentionally removed. There is only a wrapper which has an interface nearly identical to the old ndb.key class which create google.datastore.cloud key. I've added simple support for KeyProperty. Please have a look at the recent version.
