implements a new feature: "BGP Allow list."
This feature allows us to control which IP prefixes are going to be advertised via ebgp from the routes received from EBGP neighbors.
redis-py 3.0 used in master branch only accepts user data as bytes,
strings or numbers (ints, longs and floats). Attempting to specify a key
or a value as any other type will raise a DataError exception.

* No need to clean up the exising NAT rules if present, which could be created by some other process.
* Delete our rule first and add it back, to take care of caclmgrd restart.
Another benefit is that we delete only our rules, rather than earlier approach of "iptables -F" which cleans up all rules.
* Keeping the original logic to clean the NAT entries, to revist when NAT feature added in namespace.

The first partition starting point was changed to be 1M as part of this
commit: 6ba2f97f1e. On systems that are misaligned before conversion
(partition start is the first sector), the relica partition that is
left in the first MB can cause problems in Aboot and result in corruption
of the filesystem on the new aligned partition.
Zeroing this old relica makes sure that there is nothing left of the old
partition lying around. There won't be any risk of having Aboot corrupt
the new filesystem because of the old relica.

As part of consolidating all common Python-based functionality into the new sonic-py-common package, this pull request:
1. Redirects all Python applications/scripts in sonic-buildimage repo which previously imported sonic_device_util or sonic_daemon_base to instead import sonic-py-common, which was added to the 201911 branch in https://github.com/Azure/sonic-buildimage/pull/5063
2. Replaces all calls to `sonic_device_util.get_platform_info()` to instead call `sonic_py_common.get_platform()` and removes any calls to `sonic_device_util.get_machine_info()` which are no longer necessary (i.e., those which were only used to pass the results to `sonic_device_util.get_platform_info()`.
3. Removes unused imports to the now-deprecated sonic-daemon-base package and sonic_device_util.py module

Fix for the host unmount issue through PR https://github.com/Azure/sonic-buildimage/pull/4558 and https://github.com/Azure/sonic-buildimage/pull/4865 creates the timeout of syslog.socket closure during reboot since the journald socket closure has been included in syslog.socket
Removed the journal socket closure. The host unmount is fixed with just stopping the services which gets restarted only after /var/log unmount and not causing the unmount issues.

Warm restart of swss will start nat which is not expected for warm
restart. Also it is observed that during warm-reboot script execution
nat container gets started after it was killed. This causes removal of
nat dump generated by nat previously:

* [sonic-buildimage] Changes to make network specific sysctl
common for both host and docker namespace (in multi-npu).
This change is triggered with issue found in multi-npu platforms
where in docker namespace
net.ipv6.conf.all.forwarding was 0 (should be 1) because of
which RS/RA message were triggered and link-local router were learnt.
Beside this there were some other sysctl.net.ipv6* params whose value
in docker namespace is not same as host namespace.
So to make we are always in sync in host and docker namespace
created common file that list all sysctl.net.* params and used
both by host and docker namespace. Any change will get applied
to both namespace.
