iPerf client pod creation failed for ipv6 traffic

[elenagerman]

Describe the bug When the ipv6 address is used for traffic generation, and this is the only ip version defined for the server -> item.status.podIP getting ipv6 ip format value, "podIP": "fd01:0:0:6::bd" as an example

As a result, the client pod failed to create because of the name format failure; only '.' and '_' are acceptable in a name string (not ':').

To Reproduce Steps to reproduce the behavior:

1. Deploy ipv6 (only) cluster

2. try to apply: ` kind: Job apiVersion: batch/v1 metadata: name: 'iperf3-client-fd01:0:0:6::85-2f8af690' namespace: 'benchmark-operator' spec: backoffLimit: 0 activeDeadlineSeconds: 3600 template: metadata: labels: app: iperf3-bench-client-2-2f8af690 benchmark-uuid: "74a7cc28-c5ea-4571-82c7-632ecba88eb2" spec: affinity: podAntiAffinity: preferredDuringSchedulingIgnoredDuringExecution:

3. [kni@registry.kni-qe-3 ~]$ oc apply -f test2.yaml The Job "iperf3-client-2fd01:0:0:6::85-2f8af690" is invalid:

   • metadata.labels: Invalid value: "iperf3-client-2fd01:0:0:6::85-2f8af690": a valid label must be an empty string or consist of alphanumeric characters, '-', '_' or '.', and must start and end with an alphanumeric character (e.g. 'MyValue', or 'myvalue', or '12345', regex used for validation is '(([A-Za-z0-9][-A-Za-z0-9.]*)?[A-Za-z0-9])?')
   • spec.template.labels: Invalid value: "iperf3-client-2fd01:0:0:6::85-2f8af690": a valid label must be an empty string or consist of alphanumeric characters, '-', '_' or '.', and must start and end with an alphanumeric character (e.g. 'MyValue', or 'myvalue', or '12345', regex used for validation is '(([A-Za-z0-9][-A-Za-z0-9.]*)?[A-Za-z0-9])?')

Expected behavior client pod should be created
