WHMCS migration tool enhancements

Feature Request

This is for the creation of a CLI-drive module for the migration of WHMCS data to Upmind via various scripts that are run (from the CLI). Module should track successes and errors as well as which object instances have been migrated in order to facilitate tracking and debugging.

How Would You Use This in Upmind?

Onboarding

What problem does this solve for you?

Makes it easier to onboard customers who have previously used WHMCS.
