SERVER-29527 Use infrastructure_provisioning.sh and infrastructure_te…

…ardown.sh

* Use infrastructure_provisioning.sh instead of setup_cluster.sh.

* The code to save and reuse terraform.tfstate in
  /data/infrastructure_provisioning/ goes into infrastructure_provisioning.sh.
  (From there, the good old setup_cluster.sh is called too.)

* Rename destroy_cluster.sh to infrastructure_teardown.sh
