This commit introduces a new package `pkg/kms`. It contains basic types and functions to interact with various KMS implementations. This commit also moves KMS-related code from `cmd/crypto` to `pkg/kms`. Now, it is possible to implement a KMS-based config data encryption in the `pkg/config` package.
