Add CryptographicAlgorithm filtering support for Locate

This change updates Locate operation support in the PyKMIP server,
allowing users to filter objects based on the object's
Cryptographic Algorithm. If an object's type does not support the
Cryptographic Algorithm attribute, that object is not a match.
Unit tests and integration tests have been added to test and
verify the correctness of this feature.

Additionally, the Locate demo scripts have also been updated to
support Cryptographic Algorithm filtering. Simply use the
"--cryptographic-algorithm" flag to specify a Cryptographic
Algorithm enumeration for the Locate script to filter on.
