CXL 3.0 Spec 8.2.9.8.3.3 defines Set Alert Configuration mailbox command which
allows a CXL host to configure programmable warning thresholds optionally.
Add methods to issue the command and set fields.

-v, --verbose turn on debug
-S, --serial use serial numbers to id memdevs
-L, --life-used-threshold <threshold>
threshold value for life used warning alert
--life-used-alert <'on' or 'off'>
enable or disable life used warning alert
-O, --over-temperature-threshold <threshold>
threshold value for device over temperature warning alert
--over-temperature-alert <'on' or 'off'>
enable or disable device over temperature warning alert
-U, --under-temperature-threshold <threshold>
threshold value for device under temperature warning alert
--under-temperature-alert <'on' or 'off'>
enable or disable device under temperature warning alert
-V, --volatile-mem-err-threshold <threshold>
threshold value for corrected volatile mem error warning alert
--volatile-mem-err-alert <'on' or 'off'>
enable or disable corrected volatile mem error warning alert
-P, --pmem-err-threshold <threshold>
threshold value for corrected pmem error warning alert
--pmem-err-alert <'on' or 'off'>
enable or disable corrected pmem error warning alert

+cxl-set-alert-config(1)
+=======================
+
+NAME
+----
+cxl-set-alert-config - set the warning alert threshold on a CXL memdev
+
+SYNOPSIS
+--------
+[verse]
+'cxl set-alert-config <mem0> [<mem1>..<memN>] [<options>]'
+
+DESCRIPTION
+-----------
+CXL device raises an alert when its health status is changed. Critical alert
+shall automatically be configured by the device after a device reset.
+If supported, programmable warning thresholds also be initialized to vendor
+recommended defaults, then could be configured by the host.
+
+Use this command to configure warning alert thresholds of a device.
+Having issued this command, the newly requested warning thresholds would
+override the previously programmed warning thresholds.
+
+To enable warning alert, set both 'threshold=value' and 'alert=on'. To disable
+warning alert, set only 'alert=off'. Other cases would cause errors.
+
+Use "cxl list -m <memdev> -A" to examine the programming warning threshold
+capabilities of a device.
+
+EXAMPLES
+--------
+Set warning threshold to 30 and enable alert for life used.
+[verse]
+cxl set-alert-config mem0 -L 30 --life-used-alert=on
+
+Disable warning alert for device over temperature.
+[verse]
+cxl set-alert-config mem0 --over-temperature-alert=off
+
+OPTIONS
+-------
+<memory device(s)>::
+include::memdev-option.txt[]
+
+-v::
+--verbose=::
+ Turn on verbose debug messages in the library (if libcxl was built with
+ logging and debug enabled).
+
+-L::
+--life-used-threshold=::
+ Set <value> for the life used warning alert threshold.
+
+--life-used-alert=::
+ Enable or disable the life used warning alert.
+ Options are 'on' or 'off'.
+
+-O::
+--over-temperature-threshold=::
+ Set <value> for the device over temperature warning alert threshold.
+
+--over-temperature-alert=::
+ Enable or disable the device over temperature warning alert.
+ Options are 'on' or 'off'.
+
+-U::
+--under-temperature-threshold=::
+ Set <value> for the device under temperature warning alert threshold.
+
+--under-temperature-alert=::
+ Enable or disable the device under temperature warning alert.
+ Options are 'on' or 'off'.
+
+-V::
+--volatile-mem-err-threshold=::
+ Set <value> for the corrected volatile memory error warning alert
+ threshold.
+
+--volatile-mem-err-alert=::
+ Enable or disable the corrected volatile memory error warning alert.
+ Options are 'on' or 'off'.
+
+-P::
+--pmem-err-threshold=::
+ Set <value> for the corrected persistent memory error warning alert
+ threshold.
+
+--pmem-err-alert=::
+ Enable or disable the corrected persistent memory error warning alert.
+ Options are 'on' or 'off'.
