Jenkins 2.60.1
JCloud Plugin 2.14

I am unable to detect image regex on jcloud configuration for google-compute-engine.
However, I can successfully detect 'Hardware ID' and 'Location ID' without an issue.

I get the following log trying to launch a jcloud slave: https://gist.github.com/plaurin84/16fb71953f7ced30a2b0813780c4e989

I've been using jcloud with this configuration for a couple of months now, I haven't changed my credentials, and I guess they work as I can still get hardware and location.
