feat: add support for more workload types

[sleepyfoodie]

Update namespace_workload_pod:kube_pod_owner:relabel recording rule to support more workload types, which now include (but not limited to):

• replicaset NEW (also supports other replicaset types e.g. Rollout)
• deployment UPDATED - fixed replicaset appearing as deployment with empty workload label, those will now appear as the new replicaset type instead
• daemonset
• statefulset
• job UPDATED - now includes support for Pod job type
• CronJob NEW (also supports other job types e.g. ScaledJob)
• barepod NEW - a pod without a controller
• staticpod NEW - a pod controlled by a static file manifest on disk
• As well as other custom pod controllers, e.g. StrimziPodSet

Unit tests for all of the above test cases have been added.

An example deployment is shown to be healthy below, which proves the individual rules are mutually exclusive (otherwise duplicate series would be rejected):

There is another non-standard workload rule missing for workloads you would see from the following query:

group by (owner_kind) (kube_pod_owner{owner_kind!="ReplicaSet", owner_kind!="DaemonSet", owner_kind!="StatefulSet", owner_kind!="Job", owner_kind!="Node", owner_kind!=""})

That should capture workload types that are directly controlled via CRDs like StrimziPodSet for example.

No join is required for this additional rule as the pods are created directly rather than via ReplicaSets.
