* Refactor: func has already access to probeID
* Allow controls for more k8s topologies
Controls for nodes generally need to know about the probe that is in
control of them.
This PR appends the probe ID info to k8s topologies CronJob, DaemonSet,
Service, and StatefulSet. Therefore allowing plugins to append controls.
* Remove superfluous error check
* Add some tests to verify controls allowance
Upgraded from 99c19923, branch release-3.0.
This required fetching or upgrading the following:
* k8s.io/api to kubernetes-1.9.1
* k8s.io/apimachinery to kubernetes-1.9.1
* github.com/juju/ratelimit to 1.0.1
* github.com/spf13/pflag to 4c012f6d
Also, update Scope's imports/function calls to be compatible with the new client.
Most of the time you only care about cronjobs, not the jobs that make them up,
so we only collect full cronjob data. We associate pods of jobs with the parent cronjob
