Gateway timeout associating bug

[opoplawski]

Trying to associate bug https://bugzilla.redhat.com/show_bug.cgi?id=2021090 with https://retrace.fedoraproject.org/faf/reports/277417 but I keep getting a 504 gateway timeout error.

This is caused by the recent change in RH Bugzilla authentication. Here is a backtrace from retrace.fp.o:

DEBUG:bugzilla._backendxmlrpc: XMLRPC call: Bug.get({'extra_fields': ['comments', 'description', 'external_bugs', 'flags', 'sub_components', 'tags'], 'ids': [2031227]})

During handling of the above exception, another exception occurred:

That is, we need to update our Bugzilla module to use the proper authentication method.

On a related note, "retrying in 90 seconds" doesn't sound so appealing. Perhaps shorten the back-off as well?

Related note: We might not need write permissions, so the authentication might not be required – the Get Bug method can be used without authn. However, authentication is required to read non-public bugs.

Note this issue was reported long before Bugzilla changes the auth method, but symptoms do look the same.

This should be fixed now. I was able to associate the report successfully.
