Created by: arussellsaw
This PR does the following:
- adds encryption key config to site config
- renames
keyring
👉 encryption
- adds subpackage
encryption/keyring
for loading keys from site config - adds
NoopKey
so we can wire stuff up without actually encrypting - loads cloud KMS keys from config
