(python-config-type-instance-18) Eliminate notion of "Regular" Config Type in core. Only Regular Type was Any
Any was the only type where this was used, so this is more
accurate. The notion of a "regular" type in the graphql layer means "Any
or Scalar" which is kind of "Scalar-ish". However not going to change
the verbiage in that layer.
Depends on D1596
