Ansible runner async method

[Ladas]

Make it possible to run ansible-runner on the background, so it doesn't block the generic worker.

@agrare ok, so this is ready for testing:

Your workflow would be:

res = AnsibleRunner.run_async(...)

if res.running?, do content = res.dump and store the content to the db
then repeat: AnsibleResponseAsync.load(content).running?

Once it is not running, fetch the you will fetch the response with:
response = AnsibleResponseAsync.load(content).response # this is the same Response object as returned by the synced version

---

For testing, you can use a simple playbook:

---
- name: Create a security group
  hosts: localhost
  connection: local
  gather_facts: False
  tasks:
    - name: simulate long running op (15 sec), wait for up to 45 sec, poll every 5 sec
      command: /bin/sleep 90
      async: 405
      poll: 5

Just don't do sleep bigger than 120s, since that will fail now ansible/ansible-runner#99 (comment)

And the run_async works now, run_role_async doesn't run on the background because of
ansible/ansible-runner#100
