Backport of https://github.com/sonic-net/sonic-buildimage/pull/12490 into 202211
- Why I did it
Support syslog rate limit configuration feature
- How I did it
Remove unused rsyslog.conf from containers
Modify docker startup script to generate rsyslog.conf from template files
Add metadata/init data for syslog rate limit configuration
- How to verify it
Manual test
New sonic-mgmt regression cases
* This was a temporary fix for orchagent spamming log messages and causing rate limiting, leading to critical messages being dropped for the syslog. No longer needed since Azure/sonic-sairedis#680 was merged.
There is currently a bug where messages from swss with priority lower than the current log level are still being counted against the syslog rate limiting threshhold. This leads to rate-limiting in syslog when the rate-limiting conditions have not been met, which causes several sonic-mgmt tests to fail since they are dependent on LogAnalyzer. It also omits potentially useful information from the syslog. Only rate-limiting messages of level INFO and lower allows these tests to pass successfully.
