This change fixes various pending deprecation warnings throughout
the library caused by recent updates to different dependencies.
While PyKMIP no longer directly triggers these warnings, some
dependencies still do when run through the test suite.
This change updates the KMIP object model to support explicitly
storing key wrapping data attributes. Key wrapping data is treated
externally as a dictionary and is stored as individual fields in
the back end. Various unit tests have been updated and added to
support these additions.
This change adds SymmetricKey to the Pie object hierarchy along with a
test suite and updates to the other classes and test suites composing
the Pie interface.
This change adds two additional abstract base classes for the Pie
ManagedObject object hierarchy: CryptographicObject and Key. Test suites
are provided for each base class, using a dummy subclass of each for
testing. The object test suite package structure is also modified to
collect all ManagedObject subclass tests in one package.
