Add IPv6 option for e2e iPerf test

The e2e iPerf test case currently only runs in IPv4 mode.
This change adds an option to run an iPerf test in IPv6 mode (i.e. by running
iPerf with a "-V" command line flag), so that the test can be run on
IPv6-only clusters.



**What this PR does / why we need it**:
This change adds an option to run an iPerf test in IPv6 mode (i.e. by running
iPerf with a "-V" command line flag), so that the test can be run on
IPv6-only clusters. It also adds a Feature tag to the current IPv4 iPerf test
so that it can be disabled when running e2e tests on an IPv6-only cluster.

**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes #53388

**Special notes for your reviewer**:
Please let me know if there are better "Feature:" tags to use for selecting whether to run the IPv4 vs IPv6 test case.

**Release note**:
