Subject: [PATCH -next 08/14] kddv/cmd: Add command to run testcases

From: Zhang Xiaoxu <zhangxiaoxu5@...wei.com>

Add command kddv.cmds.test, which can help to run the testcase
use the python unittest framework.
  $ python3 -m kddv.cmd.test
  or
  $ python3 -m kddv.cmd.test kddv.tests.hwmon.test_max31722

Also enable fault inject test or enable kmemleak check. Usage:

Enable fault inject test:
  $ python3 -m kddv.cmds.test --fault-inject=all
  or
  $ python3 -m kddv.cmds.test --fault-inject=all \
  kddv.tests.hwmon.test_max31722.TestMax31722.test_device_probe

Enable kmemleak check:
  $ python3 -m kddv.cmds.test --kmemleak

Both fault inject and kmemleak will increase the time times.
