version information goes to stderr instead of stdout

[mnohrthern]

Hey guys,

during the rollout automation of the ipmi exporter, I've recognized that the output of

ipmi_exporter --version

is send to stderr. This behavior is different to the rest of the prometheus stack, like prometheus itself, alertmanager or node exporter. All of them send version infos to stdout.

Is this intended?

expected behavior:

• Version output goes to stdout

observed behavior:

• Version output goes to stderr

Thanks for pointing that out, I never noticed this
