sample config file has syntax error (but commented out)

[Jay Buffington]

    # Add python stack traces to SQL as comment strings
    # connection_trace = False,

If you uncomment the connection_trace line without removing the trailing comma you get this error:
    2013-08-26 23:26:22.490 30871 CRITICAL neutron [-] Unexpected boolean value 'False,'

    Remove trailing comma

    Closes-Bug: #1217135

    There are trailing commas in default value of some options, uncomment
    them will cause CRITICAL error for neutron-server. These sample config
    may mislead operators, so this patch fix them to the correct format.
