This script will install the pre-requisite tooling for Tanzu Application Platform
on Ubuntu-like systems.

You may be prompted for your password for 'sudo' commands and you will
also need to supply a 'UAA API refresh token' to access files from the Tanzu
Network site. To obtain such a token:

* Go to https://network.tanzu.vmware.com
* Sign in
* Select the drop-down menu that appears when you click on your name
  at the top right-hand corner of the page
* Click on 'Edit Profile'
* At the bottom of the page click on 'Request New Refresh Token'
* Make a copy of the token
