    Calculate the hash value of  the lambda resource code path planned value or the configuration value and use it to

    the correct lambda resource.

    Parameters
    ----------
    terraform_resource: TFResource
        The mapped TF resource. This will be used to resolve the configuration value of the code attribute in the lambda
         resource
    lambda_resource_prefix: str
        a string prefix to be added to the hash value to differentiate between the different lambda resources types
    lambda_resources_to_code_map: dict
        the map between lambda resources code path values, and the lambda resources logical ids
    logical_id: str
        lambda resource logical id
    lambda_resource_code_value: Any
        The planned value of the lambda resource code path
    terraform_code_property_name: str
        The lambda resource code property name
    translated_resource: Dict
        The CFN translated lambda resource
