* [submodule] update sonic-linux-kernel (#2985)
* Fix many version strings
* Update minor version
* Update arista-drivers submodule (#9)
* Rebuild SDK on new kernel (#10)
* Set the default mac ageing time to 300 seconds
The current mac ageing was disabled, this could lead the mac address
table to increase over time and lead to resource and performance issues.

* Update the default HW ageing timer to be 600 seconds.
This is to be on the safer side where ARP update interval
is 300 seconds and SONiC does not flood when ARP is aged out.

- What I did
Currently when the system is under memory pressure, the OOM killer kicks in and kills a rogue process. Killing a rogue process can cause the device to be un-healthy leading to blackholing of the traffic.
To avoid this, configure the OOM to do a kernel panic which will cause the device to reboot and come back up healthy.
- How I did it
Added the sysctl variable panic_on_oom and set the value to 2.
Setting it to 2 will ensure OOM killer to always do a kernel panic.

* [logrotate] Decrease frequency to every 10 minutes; kill any lingering logrotate processes
* [logrotate] Delete all *.1.gz files as firstaction; Remove note about init-system-helpers < 1.47 workaround
However, continue to send SIGHUP directly to rsyslogd process
because 'service rsyslog rotate' still doesn't work properly with
init-system-helpers version 1.48

* Switch the nss look up order as "compat" followed by "tacplus".
This helps use the legacy passwd file for user info and go to tacacs only if not found.
This means, we never contact tacacs for local users like "admin".
This isolates local users from any issues with tacacs servers.
W/o this fix, the sudo commands by local users could take <count of servers> * <tacacs timeout> seconds, if the tacacs servers are unreachable.
* Skip tacacs server access for local non-tacacs users.
Revert the order of 'compat tacplus' to original 'tacplus compat' as tacplus
access is required for all tacacs users, who also get created locally.
* Change URL for isc-dhcp source repository
* Modify supervisor conf to generate dhcrelay commands with '-id' and '-iu' options
* Comments; Also clean up jinja2 syntax
* Patch relay to open one socket per interface and send to all servers on all upstream interfaces
* Patch relay agent to properly forward BOOTREQUEST only on appropriate interface if it is a directed broadcast
* Port upstream patches to isc-dhcp-relay to support upstream/downstream interfaces
* Update patch to properly support interfaces with multiple IP addresses assigned
* Pass --enable-use-sockets to configure instead of uncommenting USE_SOCKETS directly

- Add ebtables package, and install some filter rules:
1. ebtables -A FORWARD -d BGA -j DROP
2. ebtables -A FORWARD -p ARP -j DROP
Basically, we let the ARP packets in the VLAN being forwarded by the ASIC,
kernel gets a copy of these ARP packets and the forwarding from Kenerl gets
dropped. So there is always only one copy of ARP/response in the VLAN.
