[Matt Riedemann (mriedem)]

This isn't a breaking change for nova right now because the oslo.log change 7c671ea77f4d7701d0def9a9e17b6c49310ca438 that removed the verbose option isn't released yet. So yes it's deprecated and we should clean it up, it's not breaking yet unless you're using the master trunk code from oslo.log.

    baseproxy: stop requiring CONF.verbose

    Option "verbose" from group "DEFAULT" was deprecated for removal during
    Mitaka, and has been removing during Newton.

    It has been dropped by oslo.config and nova-novncproxy now fails to
    start:
    NoSuchOptError: no such option in group DEFAULT: verbose

    This patch aims to stop requiring CONF.verbose that does not exist
    anymore.
