    Do not log a warning about not using compute monitors

    The compute_monitors configuration option is empty by
    default, however, on nova-compute startup we get a warning
    logged saying:

      Excluding nova.compute.monitors.cpu monitor virt_driver. \
      Not in the list of enabled monitors (CONF.compute_monitors).

    This is unnecessary noise in the logs when nova-compute is
    not configured to use monitors, so this change avoids the warning
    log message in that case.

    The compute_monitors configuration option help text is also
    updated to (1) fix formatting and (2) remove the mention of the
    numa_mem_bw monitor which never made it into nova (see
    blueprint memory-bw).
