Output information formatting and progress display on CLI

[firnsy]

A consistently formatted information output and simplified display is needed for all template output commands.

For example, the canvas template pull command will attempt to download/install/remove packages based on the template. To do this it uses the dnf python extensions to download and perform transactions.

Currently the MultiFileProgressMeter class (from dnf.cli.progress) is used for download progress on repo and package information. There is no Meter currently used for the transaction method call.

The current mixed output, shown below, shows the inconsistencies between the dnf progress output and existing canvas outputs including:

• leading case sensitivities
• message type prefixes (eg. info, debug)

The mixed output format looks like:
