Ansible version inconsistency for Ubuntu setup

[hunhoffe]

Environment details:

• Local Deployment
• Ubuntu 18.04

Steps to reproduce the issue:

1. View documentation & scripts

Provide the expected results and outputs:

I was trying to deploy OpenWhisk using ansible for the first time on Ubuntu 18.04. However, the setup was confusing due to conflicting documentation/scripts.

On the ansible page, it specifies versions:

sudo pip install ansible==4.1.0
sudo pip install jinja2==3.0.1

However, these are not the version that are installed as part of the Ubuntu setup scripts. The versions there are significantly older:

sudo pip install ansible==2.5.2
sudo pip install jinja2==2.9.6

I'd be happy to try updating the Ubuntu Setup scripts, however I wanted to ask first if there was a reason for using the older versions of ansible and jinja?

Also, is there any desire for updating for Ubuntu 20.04/python3?

Thanks @hunhoffe - would be great to merge a PR for this.

I was also realizing that the travis setup scripts seem to be using ansible 2.8.18... I'm guessing the CI tests should align with documentation as well.

Yes. We need to update them all.
I think the new version is just not tested.
In my downstream, we are using CentOS and I tried migrating to Ansible-4.1.0 once but it didn't work for some reason.
I didn't look into it deeply because of limited time but I believe upgrading to a new version is the right way to pursue.
