Allow queries without authentication key

[juhp]

It would be nice if pdc-client could do queries without insisting on having an auth key.
Authentication is only really needed for updating PDC data.

Version

pdc-client-1.8.0-18.fc32

Steps to Reproduce:

$ pdc -s https://pdc.fedoraproject.org rpm list

Actual results:

Traceback (most recent call last):
File "/usr/bin/pdc", line 22, in
runner.run()
File "/usr/lib/python3.8/site-packages/pdc_client/runner.py", line 183, in run
self.client = pdc_client.PDCClientWithPage(self.args.server, page_size=self.args.page_size, ssl_verify=ssl_verify, page=self.args.page)
File "/usr/lib/python3.8/site-packages/pdc_client/init.py", line 407, in init
super(PDCClientWithPage, self).init(server, token, develop, ssl_verify, page_size)
File "/usr/lib/python3.8/site-packages/pdc_client/init.py", line 238, in init
token = self.obtain_token()
File "/usr/lib/python3.8/site-packages/pdc_client/init.py", line 256, in obtain_token
raise Exception('Could not obtain token from any known URL.')
Exception: Could not obtain token from any known URL.

Expected results:

Read some results without auth key.

I wasn't aware that the pdc client and server are still used. I thought fpdc (with fpdc-client) is the new cool thing.

Ah, so I wasn't aware of fpdc...

It seems to be a library?
