Optimize syslog rate limit feature for fast and warm boot (#17458)

- Why I did it
Optimize syslog rate limit feature for fast and warm boot

- How I did it
Optimize redis start time
Don't render rsyslog.conf in container startup script
Disable containercfgd by default. There is a new CLI to enable it (in another PR)

- How to verify it
Manual test
Regression test
