Deprecation warnings with Ansible 2.9.6

[aareet]

Thank you for creating and open sourcing this code! I want to report some deprecation warnings I noticed in the traceback.

Using Ansible 2.9.6 throws a few deprecation warnings:

TASK [INSTALL PIP PACKAGES] ****************************************************
[DEPRECATION WARNING]: Invoking "pip" only once while using a loop via
squash_actions is deprecated. Instead of using a loop to supply multiple items
and specifying `name: "{{ item }}"`, please use `name: ['requests',
'virtualenv', 'virtualenvwrapper']` and remove the loop. This feature will be
removed in version 2.11. Deprecation warnings can be disabled by setting
deprecation_warnings=False in ansible.cfg.

TASK [INSTALL APT PACKAGES] ****************************************************
[DEPRECATION WARNING]: Invoking "apt" only once while using a loop via
squash_actions is deprecated. Instead of using a loop to supply multiple items
and specifying `name: "{{ item }}"`, please use `name: ['software-properties-
common', 'git', 'tree', 'traceroute', 'python-dev', 'python-pip', 'python3',
'python3-pip', 'libxml2-dev', 'libxslt1-dev', 'zlib1g-dev', 'vim', 'libssl-
dev', 'libffi-dev', 'fonts-inconsolata', 'python-setuptools', 'libxml2-utils',
'xsltproc', 'ant', 'default-jdk']` and remove the loop. This feature will be
removed in version 2.11. Deprecation warnings can be disabled by setting
deprecation_warnings=False in ansible.cfg.
