fixed the hammer cli issue.

Hi, @tbrooks, from hammer perspective, there is also a PR that should fix your error [1]. Moreover, if you need Puppet support, you can install hammer-cli-foreman-puppet and apply this patch [1].

UPD: Regarding Puppet, this patch will work only for hammer-cli-foreman-puppet version 0.0.5 or above, which wasn’t released yet :confused: But otherwise it should make hammer-cli-foreman-discovery usable again.
