config files should mention default log location

[Jon Bernard]

Configuration files should mention that the default log location is stdout unless otherwise specified by the user using the 'log_file' and/or 'use_syslog' directives. This will remove potential user confusion when editing glance configuration.

Could you assign the bug to yourself since you already started working on it?

    Document default log location in config files

    It's not immediately obvious where log output will go if the 'log_file' and
    'use_syslog' directives are either missing or commented out. This patch updates
    the documentation in the config files to mention the stdout default. This
    should help remove any confusion when configuring logging for glance.
