Add Associated External Types for Collection and Object Attributes

[bendbennett]

Associated external types provide a mechanism to link a Framework type with a Go type used by an API. Associated external types have been defined for:

• primitive attributes (i.e., Bool, Float64, Int64, Number, and String attributes)
• objects within List, Map, Set, and Single nested attributes
• objects within List, Set, and Single nested blocks

In order to make the generation of methods for converting to/from Framework types to Go types possible within the Framework code generator for List, Map, Object, and Set Attributes, associated external types for List, Map, Object, and Set Attributes for data sources, provider, and resources need to be added.
