Testing update needed prior to -- theforeman/jenkins-jobs#65

Please keep the README up to date (https://github.com/theforeman/kafo#requirements).

If you're dropping this, please also drop all code for it:

kafo/lib/kafo/puppet_command.rb

Line 76 in a45b1eb

#{add_progress}

kafo/lib/kafo/puppet_command.rb

Lines 82 to 84 in a45b1eb

	def add_progress
	%{$kafo_add_progress=#{!KafoConfigure.verbose}}
	end

(and the tests)

Also, I'd like to hold this off. Doing another major release is just a pain and we don't really gain a lot by doing so now, right?

If not now, then when? If we plan to drop this support, we benefit ourselves from doing it across the board and at the start of a release. The "major" bump aspect of it is pretty easy to orchestrate. What do you see as the pain ?

Cherry picks become more work.

In #354 I went a step further and also cleaned up the progress bar support.
