* Moved ErrorCodesVersionSwitcher to //ledger/error

CHANGELOG_BEGIN
CHANGELOG_END

* Rename ErrorCodeLoggingContext to ContextualizedErrorLogger

* Refactored ErrorFactories
* All error factories use ContextualizedErrorLogger for being able to dispatch self-service error codes.
* The ContextualizedErrorLogger is passed down from the dispatching Ledger API services.
* ErrorFactoriesSpec asserts both legacy (V1) and self-service error codes (V2).

Ledger API authorization

General authorization in gRPC

An Interceptor reads HTTP headers, and stores relevant information (e.g., claims) in a Context.

GRPC services read the stored data from the Context in order to validate the requests.

Authorization in the ledger API

The AuthService defines an interface for decoding HTTP headers into Claims.

The ledger API server takes an AuthService implementation as an argument.

The ledger API server uses a call interceptor and the given AuthService implementation to to store decoded Claims in the gRPC Context.

All ledger API services use the Claims to validate their requests.
