Un-idle targets in service auto idler is not working correctly

[shreddedbacon]

The idle-services.sh script currently sets all the un-idle targets for services so that services un-idle at the same time, but it does not appear to work correctly.

When an endpoint is requested, only that service is un-idled initially before the other endpoints are requested.

This may be caused by the version of OC in use in the image.

When the service idler tries to add the idling.alpha.openshift.io/unidle-targets=${ALL_IDLED_SERVICES_JSON} it can't.
