Description

Our API returns type of any for a specific field, which can be string, int, or bool. However, it seems that the current implementation of the provider SDK does not support this (as we need to specify one primitive type). We need to find a way to handle fields of type string, int, or bool interchangeably.

Expected Behavior:

The Terraform provider SDK should provide support for fields that can accept values of multiple types, such as string, int, or bool.

Steps to Reproduce:

Specify a resource with a field that can accept values of multiple types (string, int, bool) in the Terraform provider SDK.
Attempt to create or update the resource with values of different types for the field.
Observe that the provider SDK throws an error or fails to handle the field correctly.

Actual Behavior:

The Terraform provider SDK does not support fields of type any, causing errors or incorrect handling when attempting to create or update resources with fields that can accept values of multiple types.

				Description: "right hand side value",
				Type:        schema.TypeString,          # API can respond with string, int or bool
