ndk 22.9.12

Why I did it

Optimize the missing heartbeat message. It will be logged every 30 minutes when heartbeat is missing.
The SONIC application doesn't want to reboot the linecard when it is missing the midplane heartbeat. In case the warning messages are logged more often, modify the code to log their warning in every 30 minutes.

@jon-nokia so the idea here is that after noticing and logging for the first time ( that midplane connectivity is lost ) we will wait for 30 min for the following log message.

I am referring to these syslog, Are we keeping the second log message ?

1. syslog_msg: "Unable to reach slot $USER_SLOT (Supervisor/Lincard) via Midplane"
2. syslog_msg: "Action set to reboot. Rebooting self"

@mlok-nokia also for comments.

@judyjoseph Yes. What you described above is correct. There is a second log message.
After the change of not to reboot the LC itself when heartbeat is missing for 60 seconds. A second log message which will be logged every 60 seconds on both Linecard and Supervisor. This version of NDK contains the change to log this second message every 30 minutes instead of 60 seconds.
