Add option to do iperf single-ended test from toolkit GUI

[laeti-tia]

pscheduler now has the capability of doing iperf single-ended test towards devices not running pscheduler. See perfsonar/pscheduler#456

It would be useful to be able to setup such kind of tests from the toolkit GUI. This should probably go into the Advanced Parameters section.

Need to add this flag to the GUI that sets this parameter:

single-ended: true

preferably as a sliding toggle

[apertome]

This has been implemented. Can someone (@ToniN perhaps) test and make sure this is working correctly.

The GUI parts should be good, but I'm not sure about the interface with pscheduler, specifically:
perfsonar/perl-shared@424068c#diff-c859b6223bbe9ec71f12fbde88a4d6e3R80

I am not sure what this part is supposed to look like.

Thanks!

I don't get single-ended option in toolkit-webui.json after configuring the throughput test in the toolkit GUI. Are we still missing some part for this?

I threw myself on the assignee list. The toolkit gui keeps things in the old meshconfig-agent-tasks.conf format and then converts them on save to psconfig. Right now psconfig does not know how to convert a meshconfig-agent-tasks.conf with the new single_ended option to single-ended. This will be very quick to add.

This should be fixed now. Updating to the latest libperfsonar-psconfig-perl should do the trick. Did a quick local test and it showed-up in file.

Looks good, single tests is created now and runs periodically with a remote iperf3 server.

OK great, in that case, I am closing this. Thanks, guys!
