Add location transformer, config for transformers
Location transformer helps choose the most specific transformer for
read/write operations depending on the path of resource being accessed.
Configuration allows use of --experimental-encryption-provider-config
to set up encryption providers. Only AEAD is supported at the moment.
Add new files to BUILD, AEAD => k8s-aes-gcm
Use group resources to select encryption provider
Update tests for configuration parsing
Remove location transformer
Allow specifying providers per resource group in configuration
Add IdentityTransformer configuration option
Fix minor issues with initial AEAD implementation
Unified parsing of all configurations
Parse configuration using a union struct
Run configuration parsing in APIserver, refactor parsing
More gdoc, fix minor bugs
Add test coverage for combined transformers
Use table driven tests for encryptionconfig
Kubernetes-commit: 9760d00d08ef0619e30a7b1b90fd290cab960069
Tweak the ValueTransformer interface slightly to support additional
context information (to allow authenticated data to be generated by the
store and passed to the transformer). Add a prefix transformer that
looks for known matching prefixes and uses them. Add an AES GCM
transformer that performs AEAD on the values coming in and out of the
store.
