image_ref: underscores translated to dashes

[egouraud]

Hi,

I don't know if i missed something, but when i configured an image_ref with CentOS_7 , kitchen tried to launch an OS instance with a regex for CentOS-7 (which does not exist in our image list)

in my conf file:

platforms:
  - name: centos7
      network_ref:dmz
      image_ref:CentOS_7

kitchen's result:

-----> Starting Kitchen (v1.4.1)
-----> Creating <default-centos7 network-ref:dmz image-ref:CentOS-7>...
>>>>>> Create failed on instance <default-centos7 network-ref:dmz image-ref:CentOS-7>.
>>>>>> Please see .kitchen/logs/default-centos7 network-ref:dmz image-ref:CentOS-7.log for more details
>>>>>> ------Exception-------
>>>>>> Class: Kitchen::ActionFailed
>>>>>> Message: Image not found
>>>>>> ----------------------
