add missing 'until' condition in control plane setup

[weakcamel]

This PR fixes #144
which introduced retries to network setup.

Unfortunately retries don't currently work due to missing until statement. See:
https://docs.ansible.com/ansible/latest/playbook_guide/playbooks_loops.html#retrying-a-task-until-a-condition-is-met

You must set the until parameter if you want a task to retry. If until is not defined, the value for the retries parameter is forced to 1.

This PR also increases the number of retries from 3 to 10 12 (60 sec in total); I personally did experience situations where 15 seconds were not sufficient - and I can't think of a reason to not be a bit more permissive.

@weakcamel - Thanks! And if there's ever a truly breaking change like this, please feel free to bump with an email or tweet! There's a lot of noise out there, it's easy for something like this that actually fixes an active bug to get lost :(

@geerlingguy Many thanks for reviewing and accepting this PR!

With the sheer number of your repositories I can imagine how busy it gets and how spread thin you must be at times so much appreciated.
