implement rfc090 for named nodes endpoint

[jeremymv2]

This is a first stab at implementing rfc090 (HTTP HEAD) support.
For right now, it only covers the named nodes endpoint ('/nodes/NAME'). However, it can easily be added to other endpoints as needed.

Hmm, all the build failures seem non-related to this change and from oc_id

oc_id API
  status endpoint
    GET /id/v1/status
      retuns 200 (FAILED - 1)

[thommay]

this should just land in https://github.com/chef/chef-zero/blob/master/spec/run_oc_pedant.rb#L149 since it'll always be needed.

[jeremymv2]

Thanks - makes sense!

[jeremymv2]

I can squash commits if needed.

[thommay]

Thanks Jeremy!
