Add mpath support to validate_platform_backup
The command 'system health-query-upgrade' returns the value [Fail] for the field 'Valid platform-backup partition', that happens because the lsblk command is not able to return a device path when multipath disks are used or when the root partition is under cgts--vg. To fix this, backup commands were added in case lsblk fails to return a valid path. Test Plan: PASS: Upgrade AIO-SX (with and without multipath): Valid platform-backup partition: [Ok] on "system health-query-update" PASS: Upgrade AIO-DX (with and without multipath): Valid platform-backup partition: [Ok] on "system health-query-update" PASS: Upgrade Standard (with and without multipath): Valid platform-backup partition: [Ok] on "system health-query-update" Story: 2010608 Task: 47648 Signed-off-by: Matheus Guilhermino <matheus.machadoguilhermino@windriver.com> Change-Id: I2655dd4cfe1c91a8bcd2d7d8e10ddb662a58d6ce
