Description
Major changes proposed are:
1. Rename ServerKnob->ENABLE_ENCRYPT_KEY_PROXY to
ServerKnob->ENABLE_ENCRYPTION. Approach simplifies enabling
controlling encyrption code change using a single knob (desirable)
2. Implement EncyrptKeyVaultProxy simulated interface to assist
validating encyrption workflows in simulation runs. The interface
is leveraged to satisfy "encryption keys" lookup which otherwise
gets satisfied by integrating organization preferred Encryption
Key Management solution.
Testing
Unit test to validate the newly added code
