Comment 5 for bug 1908520

We are doing some work to use charm actions as a replacement of the peer relation based iperf testing in juju status. If I'm not mistaken, using a peer relation to run this type of tests with a certain duration like 30 seconds is not scalable by design. So setting check_iperf=False and running iperf in an action should make the whole testing process shorter.

"Change run-iperf action total-run-time to seconds"
and
"unconditionally install the iperf apt package in the charm, because it should always be available for the case where the user wants to run the run-iperf action"
