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

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

Expected behavior
client pod should be created
