* Change deprecated vagrant ansible flag 'sudo' to 'become'
* Emphasize, that the name of the pip_pyton_modules is only considered in coreos
* Remove useless unused variable
* Fix warning when jinja2 template-delimiters used in when statement
There is no need for jinja2 template-delimiters like {{ }} or {% %}
any more. They can just be omitted as described in https://github.com/ansible/ansible/issues/22397
* Fix broken link in getting-started guide
- Refactor 'Check if bootstrap is needed' as ansible loop. This allows
to add new elements easily without refactoring. Add pip to the list.
- Refactor 'Install python 2.x' task to run once if any of rc
codes != 0. Actually, need_bootstrap is array of hashes, so map will
allow to get single array of rc statuses. So if status is not zero it
will be sorted and the last element will be get, converted to bool.
