      .Watchdog device listing provides more detailed information

      Before this update, when listing available watchdog devices, the output only displayed the device path, such as `/dev/watchdog0`. This made it difficult for administrators to distinguish between multiple devices on the same system.

      With this update, the output includes the device path, identity, and driver for each watchdog. This allows for easy identification and selection of the correct device.

      Original description:

      Description of problem

      The current output of `pcs stonith sbd watchdog list` provides only the /dev/watchdog* names of the devices. This is not very useful without taking the additional step of running `wdctl /dev/watchdog<num>` to check the identity of the device (especially if a machine has multiple watchdog devices available).

       

      [root@rhel-8-0-3 sosreport-rhel-8-0-3-00000000-2019-02-05-mpoisxd]# pcs stonith sbd watchdog list
Available watchdog(s):
  /dev/watchdog
  /dev/watchdog0
[root@rhel-8-0-3 sosreport-rhel-8-0-3-00000000-2019-02-05-mpoisxd]# wdctl /dev/watchdog0
Device:        /dev/watchdog0
Identity:      i6300ESB timer [version 0]
Timeout:       30 seconds
Pre-timeout:    0 seconds
FLAG           DESCRIPTION               STATUS BOOT-STATUS
KEEPALIVEPING  Keep alive ping reply          1           0
MAGICCLOSE     Supports magic close char      1           0
SETTIMEOUT     Set timeout (in seconds)       0           0

       

      The `sbd query-watchdog` command, in contrast, prints the identity of the watchdog device.

      [root@rhel-8-0-3 sosreport-rhel-8-0-3-00000000-2019-02-05-mpoisxd]# sbd query-watchdog
Discovered 2 watchdog devices:
[1] /dev/watchdog
Identity: i6300ESB timer
Driver: <unknown>
[2] /dev/watchdog0
Identity: i6300ESB timer
Driver: <unknown>

      It would be nice for the `pcs` subcommand to include the identity of the device(s).

      Version-Release number of selected component (if applicable)

      pcs-0.10.0.alpha.6-2.el8.x86_64

      How reproducible

      Always

      Steps to Reproduce

      Run `pcs stonith sbd watchdog list` on a machine where sbd is installed.

      Actual results

      Only the /dev/watchdog* names of the devices print.

      Expected results

      The /dev/watchdog* names and the identities of the devices print.

      Additional information

      We could consider a similar addition to the `pcs stonith sbd config` output. (Node rhel-8-0-4 is offline below.)
