Cleanup via Ansible

+ Remove dependency on topo_ scripts that depends on custom SSH()
  that depends on framework itself. This way the cleanup is independent
  of failure in our SSH libs.
+ Simple ansible command can do cleanup of a machine:
  ansible-playbook --inventory inventories/lf_inventory/hosts site.yaml \
  --limit '10.32.8.18' --tags 'cleanup'
+ Add vpp_device reset and cleanup.
+ Remove historical scripts.

- Still in testing beta phase.
  - Need to add SRIOV cleanup.
