6dcc08e36c [psud]: Fix for psud crash because of database connection reset (#3647)
When database service is down, psud daemon throws an error because of DB connection reset, this because pmon service has no dependency with database service.

To resolve this issue, added database service dependency to the pmon service.

Also, increased the net.core.somaxconn value to 512 to solve the connection failure on the scaled setup.

3548587b73 [apt] Instruct apt-get to NOT check the "Valid Until" date in Release files (#3973)
This is an addendum to #3958, which also instructs apt to ignore the "Valid Until" date in Release files inside the slave containers, making a complete solution, much like the previously abandoned PR #2609. This patch also unifies file names and contents.

When the Debian team archives a repo, it stops updating the "Valid Until" date, thus apt-get will not apply updates for that repo unless we explicitly tell it to ignore the "Valid Until" date. Also, this has become an issue with active (i.e., non-archived) repos twice in the past year because the Debian folks seem to occasionally let the expiration lapse before updating the date. This will cause SONiC builds to fail with a message like E: Release file for http://debian-archive.trafficmanager.net/debian-security/dists/jessie/updates/InRelease is expired (invalid since 3d 3h 11min 20s). Updates for this repository will not be applied. until the dates have been updated and propagated to all mirrors. With this patch, SONiC should no longer be affected by lapsed "Valid Until" dates, whether they be accidental or purposeful.

* Add python packages to docker

* Build fix for docker with python packages

* added libyang as dependent package

* Allow building images on NFS-mounted clones

Prior to this change, `build_debian.sh` would generate a Debian
filesystem in `./fsroot`. This needs root permissions, and one of the
tests that is performed is whether the user can create a character
special file in the filesystem (using mknod).

On most NFS deployments, `root` is the least privileged user, and cannot
run mknod. Also, attempting to run commands like rm or mv as root would
fail due to permission errors, since the root user gets mapped to an
unprivileged user like `nobody`.

This commit changes the location of the Debian filesystem to `/fsroot`,
which is a tmpfs mount within the slave Docker. The default squashfs,
docker tarball and zip files are also created within /tmp, before being
copied back to /sonic as the regular user.

The side effect of this change is that the contents of `/fsroot` are no
longer available once the slave container exits, however they are
available within the squashfs image.

4ba0ff25d2 [services] make snmp.timer work again and delay telemetry.service (#3742)
Delay CPU intensive services at boot

- How I did it
Made snmp.timer work and add telemetry.timer.
But this is not enough because it breaks the existing snmp dependency on swss.
So, in this solution snmp timer is a wanted by swss service, but since OnBootSec timer expires only once it will not trigger snmp service, so I added line "OnUnitActiveSec=0 sec" which will start snmp service based on the last time it was active. On boot only OnBootSec will expire, on swss start/restarts only second timer will expire immediately and trigger snmp service.
However, snmp service will not stop after "systemctl stop snmp" because of the second timer which will always expire when snmp service because unavailable.
So there is a conflict which will be handled by systemd if we add "Conflicts=" line to both snmp.service and snmp.timer.

So during boot:

snmp does not start by default
swss starts and starts snmp timer
OnUnitActiveSec=0 does not expire since there is no snmp active
OnBootSec expires and starts snmp service and snmp timer gets stopped
During "systemctl restart swss"

snmp stops because of Requisite on swss
snmp unblocks snmp timer from running
swss starts and starts snmp timer
OnUnitActiveSec=0 expires imidiately and start snmp which stops snmp timer
During "systemctl stop snmp"

stop of snmp service unblocks snmp timer but no one starts the timer so it is not started by "OnUnitActiveSec=0"

[swss service] flush fast-reboot enabled flag upon swss stopping (#3908)
If we need to stop swss during fast-reboot procedure on the boot up path,
it means that something went wrong, like syncd/orchagent crashed already,
we are stopping and restarting swss/syncd to re-initialize. In this case,
we should proceed as if it is a cold reboot.

Corefile uploader service (#3887)
* Corefile uploader service

1) A service is added to watch /var/core and upload to Azure storage
2) The service is disabled on boot. One may enable explicitly.
3) The .rc file to be updated with acct credentials and http proxy to use.
4) If service is enabled with no credentials, it would sleep, with periodic log messages
5) For any update in .rc, the service has to be restarted to take effect.

* Remove rw permission for .rc file for group & others.

* Changes per review comments.
Re-ordered .rc file per JSON.dump order.
Added a script to enable partial update of .rc, which HWProxy would use to add acct key.

* Azure storage upload requires python module futures, hence added it to install list.

* Removed trailing spaces.

* A mistake in name corrected.
Copy the .rc updater script to /usr/bin.

cda61290ac [config-setup]: create a SONiC configuration management service (#3227)
* Create a SONiC configuration management service
* Perform config db migration after loading config_db.json to redis DB
* Migrate config-setup post migration hooks on image upgrade

config-setup post migration hooks help user to migrate configurations from
old image to new image. If the installed hooks are user defined they will not
be part of the newly installed image. So these hooks have to be migrated to
new image and only then they can be executing when the new image is booting.

The changes in this fix migrate config-setup post-migration hooks and ensure
that any hooks with the same filename in newly installed image are not
overwritten.

It is expected that users install new hooks as per their requirement and
not edit existing hooks. Any changes to existing hooks need to be done as
part of new image and not post bootup.

4007d9ba9c [ntp]: modified ntp script to hide the error related to cfggen (#3745)
This PR is to handle the issue 3527.
When device boots up, NTP throws a traceback as explained in the issue 3527.

- Traceback will be seen when MGMT_VRF_CONFIG does not exist in the database. Traceback is coming from the script “/etc/init.d/ntp”.

- Traceback does not affect the NTP functionality with/without management VRF. When MGMT_VRF_CONFIG does not exist or when MGMT_VRF_CONFIG’s mgmtVrfEnabled is configured to “false”, “NTP” will be started in the “default VRF” context, which is working fine even with this traceback.

- This traceback error will be hidden by redirecting the error to /dev/null without affecting functionality.

* In the event of a kernel crash, we need to gather as much information
as possible to understand and identify the root cause of the crash.
Currently, the kernel does not provide much information, which make
kernel crash investigation difficult and time consuming.

Fortunately, there is a way in the kernel to provide more information
in the case of a kernel crash. kdump is a feature of the Linux kernel
that creates crash dumps in the event of a kernel crash. This PR
will add kermel kdump support.

An extension to the CLI utilities config and show is provided to
configure and manage kdump:
 - enable / disable kdump functionality
 - configure kdump (how many kernel crash logs can be saved, memory
   allocated for capture kernel)
 - view kernel crash logs
