Support extracting common values from embedded structures
This change also added support for excluding properties from common
value extraction by using a struct tag of `sdk:"keep"` That was needed
to prevent the fields in SdkMemberPropertiesBase from having their
values cleared.
The purpose of this change is to make it easier to share functionality
across sdk member types.
