[determine-reboot-cause] Support 'Kernel Panic' reboot cause (#7153) 
Signed-off-by: Yong Zhao yozhao@microsoft.com

Why I did it
If device reboot was caused by kernel panic, then we need retrieve and store the key information into the symbol file previous-reboot-cause.json. The CLI show reboot-cause will read this file to get the reason of previous reboot.

This PR is related to PR in sonic-utilities repo: Azure/sonic-utilities#1486

How I did it
The string variable previous_reboot_cause will be parsed to check whether it contains the keyword Kernel Panic. If it did, then store the keyword and time information into a dictionary.

How to verify it
I verified this change on a virtual testbed.

admin@vlab-01:/host/reboot-cause$ more previous-reboot-cause.json
{"gen_time": "2021_03_24_23_22_35", "cause": "Kernel Panic", "user": "N/A", "time": "Wed 24 Mar 2021 11:22:03 PM UTC", "comment": "N/A"}

admin@vlab-01:/host/reboot-cause$ show reboot-cause
Kernel Panic [Time: Wed 24 Mar 2021 11:22:03 PM UTC]
