useless iso8601 debug info displayed if use "--debug"

[Liusheng]

if I use "keystone --debug user-list", CLI will display useless iso8601 debug info like:

DEBUG:iso8601.iso8601:Got u'2014' for 'year' with default None
DEBUG:iso8601.iso8601:Got u'05' for 'monthdash' with default 1
DEBUG:iso8601.iso8601:Got 5 for 'month' with default 5
DEBUG:iso8601.iso8601:Got u'29' for 'daydash' with default 1
DEBUG:iso8601.iso8601:Got 29 for 'day' with default 29
DEBUG:iso8601.iso8601:Got u'10' for 'hour' with default None
DEBUG:iso8601.iso8601:Got u'52' for 'minute' with default None
DEBUG:iso8601.iso8601:Got u'54' for 'second' with default None

additionally, other projects like ceilometer, use keystoneclient use "--debug" parameter in their commands, CLI will also display the iso8601 debug info (e.g. ceilometer --debug alarm-list), this is because other clients must call keystoneclient to get token.

    Set the iso8601 log level to WARN

    When use "--debug" parameter in other projects's CLI, it may display
    useless iso8601 debug info, this is because other client's CLI will
    call keystoneclient to get token, and keystoneclient will display the
    iso8601 debug info.

    set the iso8601 log level to "WARN" to avoid this issue.

    Improve --debug logging output

    This change makes the following improvements to the output of a heat
    command with the --debug option set:
    * Silences spurious logging from iso8601 and urllib3.connectionpool
    * Removes the line number from the logging format, since the intent
      of --debug is to show the user what network requests are occuring.
