nova-manage isn't logging errors

[Dan Prince]

Recent version of nova-manage (Folsom +) seem to not log any useful output when and error occurs.

For example:

[dprince@dovetail nova]$ ./bin/nova-manage logs syslog
Command failed, please check log for more info

** Looking in /var/log/nova/nova-manage.log shows nothing.

A variety of other commands behave the same way.

On Essex errors like this were logged to the console:

$ ./bin/nova-manage logs syslog
Command failed, please check log for more info
2012-07-26 13:48:28 CRITICAL nova [-] [Errno 13] Permission denied: '/var/log/messages'

We need to log things *somewhere* when commands like this fail. Logging to the console seems reasonable if logging hasn't been configured. Otherwise things should go to the log file.

    Sync w/ latest openstack common log.py.

    Includes the following updates for openstack-common's log.py:

        Remove code to clear basicConfig root log handlers

        Removes some old Nova specific code to clear out the log handlers
        from Nova's logging basicConfig. This code is arguably Nova specific
        and doesn't really belong in openstack-common's generic logging
        configuration.

        Additionally, This code was actually removing the root logger used
    by
        some command line tools and binaries and hiding log messages that
    should
        have otherwise gone to the console.

        Fixes LP Bug #1029577.
