sphinxext uses deprecated app.info for logging

[Sean McGinnis]

Sphinx has deprecated app.info for logging in the current 1.8.1 release and it has been removed completely in the current master branch code.

sphinxext uses app.info() calls for logging. This needs to be updated so things continue to work after the next version of sphinx is released.

    Update sphinx logging to not use app object

    Logging via the application object was deprecated in sphinx 1.6 and is
    now removed in the master branch that will become 2.0. This updates our
    sphinx extension to use the recommended sphinx.util.logging instead.

    Closes-bug: #1798174

    Add local bindep.txt and update sphinx logging

    This is a combination of two commits to fix the check / gate jobs:

    1. Add local bindep.txt

    As it was announced [1] global bindep-fallback.txt was removed and now
    projects need to have a local bindep.txt to be able to install binary
    dependencies for testing.

    In documentation zuul job graphviz package ('dot' command) is needed.
    Without that the job fails with:
        dot command 'dot' cannot be run (needed for graphviz output),
        check the graphviz_dot setting
