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

etcd has support for client-cert-auth, which can be configured via the flag `--ca-file`,
when that is enabled, all the client requests must present with a client certificate,
however, the current component status check uses a single transport for all of the checks,
this is wrong, the checks should be different for each of different component, and make
each of them use different transport(tls configurations).
