pbr should not discard user-configured suppress_warnings value in sphinx config

[Doug Hellmann]

Commit 2d7c0045f402b31d6223437ba25423eeb32278e1 hard-codes the suppress_warnings setting for sphinx, which means if a user has configured that value already their setting is discarded. That means that, for example, projects that want to ignore the warning about not using remote images in their documentation will have their doc builds break.

    add image.nonlocal_uri to the list of warnings ignored

    pbr currently hard-codes the list of warnings that are to be ignored.
    Many OpenStack projects use remote images to add project "badges" based
    on tags defined in the governance repository. Ignore the warning caused
    by using remote images so we can unbreak documentation builds using
    those badges.

    comment out openstack governance badges

    Comment out the governance badge link to avoid the warning from using a
    remote image. This can be reverted when a version of pbr with the fix is
    released.
