Move /var/log to RAM for Mellanox SN2700, Nokia 7215 and Dell S6100 (#15077) (#15871)

Browse Source 
Why I did it
Move the /var/log on RAM. This is to prevent too many disk write on /var/log when mounted on disk.

Work item tracking
Microsoft ADO (number only): 17955517

How I did it
Pass kernel cmdline option "log_inram=on"

How to verify it
Mellanox SN2700
