To Reproduce

Actual behavior

Error: error when creating Traceflow, is Traceflow feature gate enabled? Traceflow.crd.antrea.io "default-pod2-to-fc00:f853:ccd:e793::2-gnb8cv6s" is invalid: metadata.name: Invalid value: "default-pod2-to-fc00:f853:ccd:e793::2-gnb8cv6s": a lowercase RFC 1123 subdomain must consist of lower case alphanumeric characters, '-' or '.', and must start and end with an alphanumeric character (e.g. 'example.com', regex used for validation is '[a-z0-9]([-a-z0-9]*[a-z0-9])?(\.[a-z0-9]([-a-z0-9]*[a-z0-9])?)*')

Additional context
Maybe we can replace : in traceflow name with - or . while processing the traceflow name.
