[Monit] Restart telemetry container if memory usage is beyond the threshold (#7645)
Signed-off-by: Yong Zhao yozhao@microsoft.com

Why I did it
This PR aims to monitor the memory usage of streaming telemetry container and restart streaming telemetry container if memory usage is larger than the pre-defined threshold.

How I did it
I borrowed the system tool Monit to run a script memory_checker which will periodically check the memory usage of streaming telemetry container. If the memory usage of telemetry container is larger than the pre-defined threshold for 10 times during 20 cycles, then an alerting message will be written into syslog and at the same time Monit will run the script restart_service to restart the streaming telemetry container.

How to verify it
I verified this implementation on device str-7260cx3-acs-1.
