Include _locale Field in Document Response

[jessrynkar]

Description

Add an opt-in option to include the _locale field in each document response. This allows clients to explicitly identify which locale the returned document corresponds to, especially useful when a requested locale does not exist and a fallback document is returned.

Details

• Provide a query parameter or config option to enable inclusion of _locale in the response.
• The _locale field indicates the actual locale of the returned document.
• This will not be default behavior, but an opt in feature.

ETA

TBD
