foreman-installer --upgrade-puppet outputs lots of yum command info
If you run 'foreman-installer --upgrade-puppet', the yum command that are run will output to stdout/stderr. This creates quite a bit of extraneous output.
Instead, the yum commands should only output if there was a nonzero return code.
NOTE: we may want to just add a "no output on success" option to the execute method in hooks/boot/01-helpers.rb to accomplish this.
