Remove queue declaration and fix docs jobs

This commit combines the following changes:

* Remove lingering queue declaration from .zuul.yaml file.

    https://review.opendev.org/859777 (master)
    Co-authored-by: Matthias Runge <mrunge@redhat.com>

* Replace oslo_utils.fnmatch with fnmatch

    The oslo_utils.fnmatch module was added to solve an
    issue in py2.7 but it is no longer required because
    py2.7 is no longer supported. The module was deprecated
    since oslo.utils 4.9.1[1] and the stdlib's fnmatch
    module should be used instead.
