For port forwarding, log streming and rsyinc the tooling requires an oc binary to be installed on the local machine. The user is asked to to set the location of this binary in the OpenShift 3 preferences. He can do this either manually by browsing and pointing to the binary or by hitting "Restore Defaults" which looks it up in the $PATH.

We should lookup the binary in $PATH if the user doesnt provide anything, we should not error and tell the user to set the location as we do currently.
