This change adds some additional logging statements when processing
individual KMIP operations, providing additional information on
operation input and output. The associated tests have been updated
accordingly.
This change adds the KmipEngine, the core processing component of the
KmipServer. The KmipEngine contains the KMIP application logic and
handles process request messages by batch. The engine handles logging
and error handling throughout the processing stack.
New server exceptions are added to handle new error cases. A test suite
is included.
