Add basic support for parsing enums to integer or string values.

Hey,

I've been trying to add basic support for parsing enums as string or integer values and added tests. All pass. :-)

Happy to change things if needed.

Hi, thanks for your contribution.

I'm having a look at the openapi docs for enums and it seems we may go a bit further and also specify all possible values for this enum.

This will give a nice dropdown in Swagger to pick the valid values for the Enum:

As far as implementation goes. I would take a slightly different approach, where we use openapi_schema_resolver to recursively resolve int or str based on the Enum class we got.

def resolve_enum(openapi_schema_resolver: "OpenApiSchemaResolver", data_type: type):
    if not isinstance(data_type, enum.EnumMeta):
        return

    openapi_schema = openapi_schema_resolver.get_schema(data_type.__base__)
    openapi_schema["enum"] = [member.value for member in data_type]

    return openapi_schema

Hi,

yes - makes sense. Do you want me to add something?

Suggested change

	def resolve_enum(openapi_schema_resolver: "OpenApiSchemaResolver", data_type: type):
	if not isinstance(data_type, enum.EnumMeta):
	return
	openapi_type = OPENAPI_TYPE_MAP.get(data_type.__base__)
	return {"type": openapi_type}
	def resolve_enum(openapi_schema_resolver: "OpenApiSchemaResolver", data_type: type):
	if not isinstance(data_type, enum.EnumMeta):
	return
	openapi_schema = openapi_schema_resolver.get_schema(data_type.__base__)
	openapi_schema["enum"] = [member.value for member in data_type]
	return openapi_schema

if you can apply these changes I'll merge, test and release
