Ansible git move

+ Better accessibility
+ Compliant with fdio.infra._function_
  - function [pxe|terraform|ansible|vagrant]
+ dill==0.3.3 also applied on TBs
  - ci-man to follow today
- Docs to be updated in separate patch

+  # brought online, the watchdog will be started based on the mask value.
