Tear down lab

The teardown_lab.yml playbook deletes all the sandbox instances as well as local inventory files.

To destroy all the EC2 instances after training is complete:

1. Login to the Ansible host ansible_server_provioner

2. Run the playbook with the same var files used to provision the infrastructure

   cd f5_provisioner/provisioner
   ansible-playbook teardown_lab.yml -e @f5_vars.yml
