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
Major changes includes:
1. Add a new FDB role responsible- EncyrptKeyProxy. The role is
responsible to expose APIs to fetch encyrption keys interacting
with external Encryption KeyManager interface.
2. The process is a FDB singleton process following similar recruitment
rules as other singleton processes in the system.
3. Code to recruit the worker process; given the encryption keys are
needed during recovery (decode TLog records), for now the process
is co-located in same datacenter as ClusterController.
4. Skeleton process actor code; more functionality will be added in
subsequent PRs.
NOTE: The code is protected under a SERVER_KNOB with the default
value as 'false' for now.
