standardize console text coloration for all messaging

[blackboxsw]

UA client needs a common approach to text coloration in the event of error, success and warning messages across every subcommand.

Work Items:

• [ ] Define logic to automatically automatically disable or enable coloration or any text based on the detected terminal type
• [ ] Define a CLI parameter to override text color options
• [ ] Define a uaclient config override for text coloration defaults
