Subject: [PATCH] Define kernel mismatch alarms: 100.120, 100.121

2 new alarms:

- 100.120 - Controllers running mismatched kernels
  (minor, non-management affecting)

- 100.121 - Host not running the provisioned kernel
  (major, management affecting)

Part of the kernel switchover feature

Task: 48281
Story: 2010731

Test plan:
PASS - AIO-DX - install iso and bootstrap

PASS - AIO-DX - raise and clears both alarms: 100.120, 100.121
