The upstream module has seen significant work making
the v1 emulation layer a high fidelity re-implementation
of v1 "encoding/json".
This addresses several upstream breaking changes:
* MarshalJSONV2 renamed as MarshalJSONTo
* UnmarshalJSONV2 renamed as UnmarshalJSONFrom
* Options argument removed from MarshalJSONV2
* Options argument removed from UnmarshalJSONV2

Package setting contains types for defining and representing policy settings.
It facilitates the registration of setting definitions using Register and RegisterDefinition,
and the retrieval of registered setting definitions via Definitions and DefinitionOf.
This package is intended for use primarily within the syspolicy package hierarchy,
and added in a preparation for the next PRs.
