DNS test presents different behaviour under Ubuntu and Debian

[szymontrocha]

I observed it in a fresh toolkit installations:

(Debian 12 host)

# pscheduler task http --url=www.pcss.pl
Submitting task...
Unable to determine the lead participant: At /url: 'www.pcss.pl' is not a 'uri'

(Ubuntu 20 host)

$ pscheduler task http --url=www.pcss.pl
Submitting task...
Task URL:
https://perfsonar2/pscheduler/tasks/766703c8-e542-41c0-9d64-50c8f9833834

Response Time ... PT2.519671S
Status Code ..... Not Specified

No further runs scheduled.

Questions follow:

• Is http(s) prefix strictly required in task command?
• If yes it shouldn't work in both OSes equally and we need to write it in the docs. Currently docs (or --help) don't specify it

I investigated this on EL and found the same behavior.

The pScheduler code doesn't vary between distributions and parses URLs as strings with JSON Schema's uri modifier. This may indicate a difference in libraries between distributions. Investigate upgrading JSON Schema everywhere so this works properly.
