This commit adds NTP support for management VRF using L3mdev. Config vrf add
mgmt will enable management VRF, enslave the eth0 device to the master device
mgmt, stop ntp service in default, restart interfaces-configs and restart ntp
service in mgmt-vrf context. Requirement and design are covered in mgmt vrf
design document.

- ndisc6, which performs ICMPv6 Neighbor Discovery in userland,
- rdisc6, which performs ICMPv6 Router Discovery in userland,
- rltraceroute6, a UDP/ICMP IPv6 implementation of traceroute,
- tcptraceroute6, a TCP/IPv6-based traceroute implementation,
- tcpspray6, a TCP/IP Discard/Echo bandwidth meter,
- addrinfo, easy script interface for hostname and address resolution,

This commit adds support for New feature management VRF using L3mdev. Added
commands to enable/disable management VRF. Config vrf add mgmt will enable
management VRF, enslave the eth0 device to the master device mgmt and restart
interfaces-configs in mgmt-vrf context.
management interface (eth0) can be configured using config interface eth0 ip
add command and removed using config interface eth0 ip remove command.
Requirement and design are covered in mgmt vrf design document. Currently show
command displays linux command output; will update show command display in next
PR after concluding what would be the output for the show commands. Added
metric for default routes in dhcp and static, any changes for metric will be
addressed subsequently after discussing.

- What I did
Configure sshd to close all SSH connetions after 15 minutes of inactivity.
- How I did it
Set ClientAliveInterval to 900 (900 seconds = 15 minutes) and ClientAliveCountMax to 0
in /etc/ssh/sshd_config using augtool in build_debian.sh. In the process, I refactored the existing augtool command for sshd_config so as to add comments and empty lines to file for readability.
- How to verify it
Log into device via management port. Wait 15 minutes without sending a keystroke -- you should be automatically logged out.
* Added debug symbols to many debug dockers.
* For debug images *only*:
1) Archive source files into debug image
2) Archived source is copied into /src
3) Created an empty dir /debug
4) Mount both /src as ro & /debug as rw into every docker
5) Login banner will give some details on /src & /debug
6) Devs can copy core file into /debug and view it from inside a container.
7) Dev may create all gdb logs and other data directly into /debug.
* Dropped redundant REDIS_TOOLS per review comments.
* Added debug symbols to frr package and hence FRR based BGP docker.
* 1) Moved dbg_files.sh to scripts/
2) Src directories to archive are now collected from individual Makefiles.
3) Added few more debug symbols
4) Added few more debug dockers.
Here after no more changes except per review comments.
To debug:
Install required version of debug image in Switch or VM.
Copy core file into /debug of host
Get into Docker
gdb /usr/bin/<daemon> -c /debug/<your core file>
set directory /src/... <-- inside gdb to get the source
For non-in-depth debugging:
Download corresponding debug Docker image (docker-...-dbg.gz) to your VM
Load the image
Run image with entrypoint as 'bash' with dir containing core mapped in.
Run gdb on the core.
* [submodule] update sonic-linux-kernel
* update linux kernel version
* Fix many version strings
* update mellanox components (built with new kernel)
* [mlnx] add make files for SDK WJH libs
* Update arista driver submodule (#8)
Make the debian packaging point to a newer kernel version.
- 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.
- 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.

We are going to use initramfs hook for firmware upgrades
To install Arista hook:
- create folder /mnt/flash/<image dir>/platform/hooks/boot1/ from Aboot or
/host/<image dir>/platform/hooks/boot1/ from Sonic
- add executable script to created folder
* [build]: put stretch debian packages under target/debs/stretch/

* for python-based debian packages, since they are really the same for jessie and stretch, they are placed under target/python-debs directory.

When rebooting without the platform_reboot plugin, systemd takes a few
minutes to properly shutdown. It's blocking on some docker cleanup
operation.
As described by https://github.com/docker/for-linux/issues/421 there
is a race between docker.service and containerd.service.
docker needs containerd to properly stop the containers.
