* [dhcp-relay]: Add DHCP Relay Monitor (#3886)
DHCP relay MONitor (dhcpmon) keeps track of DORA messages. If DHCP Relay
is detected to be not forwarding DORA message, dhcpmon will log such event
to syslog. Under the hood dhcpmon keeps counts of clients DR messages,
forwarded DR messages, DHCP server OA messages, and forwarded OA messages.
dhcpmon will check every 12 sec (configurable) if counts are monotonically
increasing and record snapshot of those counters. dhcpmon will report
discrepancies when detected between current counters and snapshot counters.

* Add patches to series file and apply using stgit
* Update .gitignore in order to ignore downloaded and generated files
* Reorganize src/ subdirectories alphabetically in .gitignore
- 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)
* Add docker-dhcp-relay/Dockerfile to .gitignore
* Add isc-dhcp-relay .deb package to image build process, along with my Option 82 patch
* Install custom isc-dhcp-relay in dhcp_relay docker
* Install isc-dhcp-relay build dependencies in sonic-slave Docker container
* Copy the built .deb package to the destination directory
* Add dependencies for isc-dhcp-relay
* Change Option 82 string to '<hostname>:<portname>'
* Install dependencies of .deb files implicitly in Dockerfile
* Remove unused line
* Remove unnecessary space
- Consolidate config.sh and start.sh scripts into one script (start.sh)
- Solve issue #435 - All dockers now run supervisord as their ENTRYPOINT
- All stdout/stderr output from processes managed by supervisord is now sent to syslog instead of their own files
- Supervisord log messages are now also sent to syslog
- Removed unused smartmontools package from docker-platform-monitor
( All device-specific files now reside under /device directory in a <vendor-name>/<platform-string>/<hardware-SKU> directory structure in repo.
* Device-specific files are now packaged into a Debian package (sonic-device-data) and are now installed to /usr/share/sonic/device/<platform-string>/<hardware-SKU>/ directory on switch.
* [docker-config-engine]: introduce docker sonic config engine
sonic config engine provide the sonic configure engine for all sonic
dockers that rely on the engine to generate runtime configuration.
