    Avoid printing log options multiple times

    This patch ensures log_opt_values is invoked only once, thus
    avoiding annoying multiple dumps of options values.

    Note that is rpc_workers is greater than 0 a second dump will
    be logged. This patch does not address this as REST and RPC
    servers are going to be separated as a part of the feature/pecan
    work.
