[SYSTEMDS-2568] Initial Federated Privacy Support

- Privacy Constraint support for GLM
- Privacy tests for GLM
- Improved exception handling of federated responses
- Log of checked privacy constraints

This is to give the federated master information about which privacy
constraints were violated and to be able to throw the actual exception
on the master side.

Add Initial Implementation of Checked Privacy Constraints Log

This will enable the user to check which privacy constraints were
retrieved during handling of federated instruction. This is an initial
implementation since the checked privacy constraints are added to the
federated response, but this is never retrieved by the federated master.
If the privacy constraint is null for a checked data object, this is
currently not logged. This could easily be changed by moving the put
operation before the privacy constraint null check in the
PrivacyMonitor.

Closes #946
