Felipe Monteiro 8bf4f7407d Revamp document hashing ... This PS revamps document hashing. Instead of relying on Python's built-in hash function to hash the contents of a document (i.e. metadata and data values), sha256 from hashlib is used instead, mostly for security purposes. Further, new parameters have been added to the document DB model: data_hash and metadata_hash, and the old value hash has been dropped. The data type for storing the hashes has been changed to String from BigInt. Finally, testing documentation was added. Change-Id: I428ddcbce1007ea990ca0df1aa630072a050c722		2017-10-02 18:09:13 +01:00
