Works fine, one observation though, if I don't specify --path I'm getting following error

bin/hammer arf-report download --id 1675
Could not download the Arf report:
  Error: can't dup NilClass

Also it would be great if I got better error message if smart proxy is down, I'm getting this atm

Could not download the Arf report:
  Missing template api/v2/errors/ERF12-1731 [ProxyAPI::ProxyException]: Unable to get XML version of requested report from Smart Proxy ([Errno::ECONNREFUSED]: Connection refused - connect(2) for "foreman.example.tst" port 8443) for proxy https://foreman.example.tst:8443/compliance with {:locale=>[:en], :formats=>[:json], :variants=>[], :handlers=>[:erb, :builder, :raw, :ruby, :rabl]}.

although I'm not sure if this should be addressed in foreman_openscap API PR

other than that 👏

actually the issue when proxy is down is correct, the only confusing part is about missing template but all other important info is there, so just the empty --path deserves a fix :-)

[xprazak2]

I made a small cosmetic change here and updated this as well, you should get a pretty message when proxy is down.
