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.

Add changes for syslog support for containers running in namespaces on multi ASIC platforms.
On Multi ASIC platforms
Rsyslog service is only running on the host. There is no rsyslog service running in each namespace.
On multi ASIC platforms the rsyslog service on the host will be listening on the docker0 ip address instead of loopback address.
The rsyslog.conf on the containers is modified to have omfwd target ip to be docker0 ipaddress instead of loopback ip

Previously use / to separate container name and program name.
However, in rsyslogd:
Precisely, the programname is terminated by either (whichever occurs first):
end of tag
nonprintable character
‘:’
‘[‘
‘/’
The above definition has been taken from the FreeBSD syslogd sources.

- Move all minigraph-related action from rc.local to updategraph
- updategraph service is now after database. All feature services are now after and depending on updategraph
Modify minigraph parser output format so it fit DB schema
Modify configuration templates to fit new schema
Systemd services dependencies are modified so database starts before any configuration consumer
* [rsyslog]: Use timegenerated instead of timestamp
This is useful when rsyslog is used to put markers generated on other machines.
This way all messages will have a timestamp from a single system.
* [rsyslog] Use subseconds from local machine
- Force log rotation at size thresholds only (no longer also rotating logs daily), allowing for more consistent archived log size
- Eliminate remaining duplicate log messages
- Cron facility now only logs to cron.log (was also logging to syslog)
- Debug, mail, news and user log facilities only log to syslog; no longer creating separate log files for these facilities
- Cron job that calls logrotate every minute now uses the main /etc/logrotate.conf file so as to check/rotate all logs every minute, not just the logs specified in the rsyslog file. Also redirecting output of this command to /dev/null to prevent "(CRON) info (No MTA installed, discarding output)" messages in cron.log due to lack of a mail service
- Delete archive files based on remaining /var/log partition space. Note that this solution currently requires a minimum /var/log partition size of 32MB to function correctly
- Update sonic-sairedis and sonic-swss submodules to incorporate recording file name changes
- Add .screen file to .gitignore (unrelated)
- Now that logrotate is a cron job that runs every minute, it was polluting syslog
- Also shrink max size of less-important logs to 50MB and rotate them daily by default
* Rename 'ACSFileFormat' -> 'SONiCFileFormat'
* Rename '00-acs.conf' -> '00-sonic.conf'
* Add logrotate.d and systemd-journald config files to image
* Log all SONiC process messages to /var/log/syslog; prevent duplicate logging to /var/log/messages
* Do not redirect cron and daemon logs to their own files, let them log to /var/log/syslog
* Log all teamd messages to /var/log/teamd.log; Add more SONiC program names to SONiC rules clause
* Remove duplicate code by condensing quagga programs into a list; Fix teamd log rule
* Kernel and LPR messages no longer getting duplicated to their own log files
* Now calling logrotate every minute via cron job
* Need full path to logrotate in cron job
* Add '.log' suffix to wildcards, otherwise logrotate will rotate already-rotated logs (e.g., bgpd.log.1.1.1.1.1...)
* Add microsecond granularity to syslog messages
* Don't overwrite system crontab, instead, install additional logrotate crontab file into /etc/cron.d
* Removed incomplete concept of per-process SONiC logs. We can revisit again later
* Single image
* Fix review comments
* Update syncd service. Add HW mgmt to Mellanox single image.
* Add single image template for Broadcom platform.
SKU should be provided during configure:
make configure PLATFORM=broadcom SKU=Force10-S6000
* Add single image template for Cavium platform.
SKU should be provided during configure:
make configure PLATFORM=cavium SKU=AS7512
* Add description to sonic_debian_extension.j2 file.
