DXCDT-500: auth0_import.tf file creation function

[willvedd]

🔧 Changes

Introducing the createImportFile function which accepts data about import blocks, formats that data and creates a auth0_import.tf file in the specified directory. This file is then used in subsequent steps to facilitate automatic configuration generation.

It introduces a ImportResource type that standardizes the contract between this new function and the rest of the process.

Sample Output import.tf

# This file automatically generated via the Auth0 CLI.
# It can be safely removed after the successful generation 
# of TF resource definition files.

import {
	id = "con_FJVIi4jt1aQWwvoG"
	to = auth0_connection.sms
}
import {
	id = "con_DW1Ii5Tb4aEkvtoE"
	to = auth0_connection.email
}
