Anirudh Rayabharam dd66eb834c ci: dump kernel logs in MSHV workflow
Dump kernel logs after running the tests in the MSHV workflow to help
debug failures.

In addition to getting the kernel logs using `dmesg` also use AzCli to
retrieve the serial console logs. If the VM is hung or panicked, the
workflow would be unable to SSH into it and execute `dmesg`. In this
case the serial console logs would be helpful.
