Better document ansible integration
According to the feedback of a new experimenter, some documentation on the ansible integration is missing:
- modules accessible through enoslib are Ansible modules (this is possibly already documented somewhere)
- these modules should be passed a dict with exactly the same parameters as in the Ansible doc (even though Ansible modules are documented in Yaml format)
- there are top-level parameters that can be used with any module
- special cases such as
asynch
that maps toasync
- overall strategy: one big play, several sequential plays? in particular when one action needs data from a previous action, it could be done in pure ansible (registered variables) or in python
- some real-world examples
