Add a variable to enable/disable JS challenge

[cohenaj194]

https://github.com/volterraedge/terraform-volterra-app-delivery-network/blob/main/loadbalancer.tf#L68 need to add a var to change this

[cohenaj194]

The main and staging 0.4.0-rc2 branches has been updated to include the changes.

I am seeing an issue in AC with the use of this new disable_js_challenge var:

$ terraform apply -var-file=demo.tfvars.json -auto-approve
Error: Unsupported argument
  on main.tf line 6, in module "app-delivery-network":
   6:   disable_js_challenge = var.disable_js_challenge
An argument named "disable_js_challenge" is not expected here.
ERROR: Job failed: command terminated with exit code 1

This was present in both prod and staging until I merged the changes from main into the 0.4.0-rc2 branch. I suspect that production is not automatically using the latest commit of the main branch. @madhukar32 tomorrow let's look into this so that we ensure the latest changes from main are automatically available to production.
