Select ports to connect ssh to Ansible

[inna]

There's, for example, a host:

[api]
10.0.0.1 ansible_connection=ssh ansible_ssh_user=root ansible_ssh_port=22

Here we are pointing 22 Ssh port. But some servers a different port, say, 220♪

Maybe someday you'll have an extra port for the ssh connection in case you couldn't join. 22? There's a list for Ansible to take turns.

Partly used an example from Nick Volynkin.

First, the playbook checks the ports, selects what is available and installed ansible_ssh_portafter which Ansible will be connected to the car on this port. One minus - use wait_for♪ I mean, in this case, we wait 15 seconds (that is, check 3 ports) while the ports check.
