Support for creating directories about python-etcd

[jplana]

Hi!

Yes, you can create new directories with the library (using master) and etcd 0.2.rc1 :

>>> import etcd
>>> client = etcd.Client()

# This will create the directory "directory" and set the key "key" with value "1"
>>> client.write('/nodes/directory/key', 1)

# You can now retrieve all keys within that directory using
>>> client.read('/nodes/directory')
EtcdResult(action=u'get', key=u'/nodes/directory', value=None, expiration=None, ttl=None, modifiedIndex=3, prevValue=None, newKey=False, dir=True, kvs=[EtcdResult(action=None, key=u'/nodes/directory/key', value=u'1', expiration=None, ttl=None, modifiedIndex=3, prevValue=None, newKey=False, dir=False, kvs=None)])

# Or something like
>>> [v.value for v in client.read('/nodes/directory').kvs]
[u'1']

If you're using our latest released version from pypi (0.2.1) and etcd version v0.1.2 you can:

>>> import etcd
>>> client = etcd.Client()

# This will create the directory "directory" and set the key "key" with value "1"
>>> client.set('/nodes/directory/key', 1)

# You can now retrieve all keys within that directory using
>>> client.get('/nodes/directory')
[EtcdResult(action=u'GET', index=3, key=u'/nodes/directory/key', prevValue=None, value=u'1', expiration=None, ttl=None, newKey=None, dir=False)]

# Or something like
>>> [v.value for v in client.get('/nodes/directory')]
[u'1']

@jplana In addition to the following method, Is there have any more direct way?

client.set('/nodes/directory/key', 1)

Because I just want to create an empty directory
