Helper function to verify pending data source creation.
Args:
request: A Django request object; used for secureStorageKey and sessionKey.
pendingDsKey: A data source key corresponding to the one needing verification.
Returns:
A dictionary detailing whether or not the verification was a success or failure.
In the case of success, the 'status' field of the return dictionary is 'success',
and the data source key is passed back in the 'dsKey' field.
In the case of failure, the 'status' field is set to 'error' and a 'error' field
is filled with a description of the error.
In the special case that the data source was not found, the 'status' field has
value 'notFound'.
