A single adapter configuration variable, as sent in requests (spec AdapterVarBase). Also the shape of TargetCreateRequest.adapter_variable_overrides entries.

On update, value: null means "keep the existing value" — the mechanism for leaving a secret unchanged, since secret values are never returned.
