Open Stack

I tried the doctorDriver again.  This time I was successful!  I'm still
getting an error when listing the datasources though.  I tried updating and
installing my client, but no change.

// Create the datasource
$ openstack congress datasource create doctor doctor

// List the datasources
$ openstack congress datasource list
'NoneType' object has no attribute 'items'
