* Add an ability to configure remote syslog servers
* Add an initial configuration for remote syslog
* Extend YANG module and add unit tests
#### Why I did it
Adding the following functionality to rsyslog feature:
- Configure remote syslog servers: protocol, filter, severity level
- Update global syslog configuration: severity level, message format
#### How I did it
added parameters to syslog server and global configuration.
#### How to verify it
create syslog server using CLI/adding to Redis-DB
verify server is added to file /etc/rsyslog.conf and server is functional.
#### Description for the changelog
extend rsyslog capabilities, added server and global configuration parameters.
#### Link to config_db schema for YANG module changes

- Why I did it
In to-sonic and multi-asic KVM-test, pretest sometimes failed. Reason is rsyslogd process can not start in teamd container. Because rsyslog.conf is empty caused by sonic-cfggen execute failed
- How I did it
If sonic-cfggen -d execute failed, execute without -d because the template file has the default value.
- How to verify it
Build image and test it over 40 times, all passed pretest.

Fixes#12408
Why I did it
We are running into #12408 very frequently.
This results in no syslogs from any containers as rsyslog server could not start.
some of the sonic-mgmt scripts look for log statements and error out if log is not present.
Interfaces-config service configures the loopback interface along with other interfaces. rsyslog-config reads ip address of loopback interface and generates /etc/rsyslog.conf. When this race condition happens, lo interface ip is not yet programmed and rsyslog-config ends up writing UDP server as null in /etc/rsyslog.conf.
How I did it
rsyslog-config service is started after interfaces-config service.
How to verify it
Did multiple reboots and verified that $UDPServerAddress is valid.
- Why I did it

In version 3.0.0, If a broadcast address is specified in
/etc/network/interfaces, then when ifup is run, it will fail with an
error saying `'str' object has no attribute 'packed'`. This appears to
be because it expects all attributes for an interface to be "packable"
into a compact binary representation. However, it doesn't actually
convert the broadcast address into an IPNetwork object (other addresses
are handled).
Therefore, convert the broadcast address it reads in from a str to an
IPNetwork object.
Also explicitly specify the scope of the loopback address in
/etc/network/interfaces as host scope. Otherwise, it will get added as
global scope by default. As part of this, use JSON to parse ip's output
instead of text, for robustness.

- Why I did it
Group all SONiC services together and able to manage them together. Will be used in config reload command as much simpler and generic way to restart services.
- How I did it
Add services to sonic.target
- How to verify it
Together with Azure/sonic-utilities#1199
config reload -y

- Why I did it
Move frr logs from syslog from the directory /var/log/quagga/.log to /var/log/frr/log
- How I did it
Updated the rsyslog config files.
- How to verify it
Verified the logs come into the file zebra.log and bgpd.log in the DIR /var/log/frr/log
* 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.

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.
