Creating a new datastore.entity with a key name is a pain

[jgeewax]

If I know I want to create a new Person named jim, it's a huge pain to get a handle on this entity.

What I would like to do:

entity = dataset.entity(['Person', 'jim'])
entity['age'] = 80
entity.save()

What I currently have to do:

key = Key.from_path(['Person', 'jim']).dataset(dataset)
entity = dataset.entity('Person').key(key)
entity['age'] = 80
entity.save()

This is a whole bunch of extra wiring I really shouldn't need to deal with.

#488 combined with the new ease of creating Key via #451 will make this possible. Will close out #484 when complete.

Now construction easy via:

datastore.set_default_dataset()
entity = Entity(key=Key('Person', 'jim'))
entity['age'] = 80

Future PRs may even allow specifying age=80 in the constructor.
