* Updated the comments in the code.
* 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.
* Missing updates to log_info call.
redis-py 3.0 used in master branch only accepts user data as bytes,

We are moving toward building all Python packages for SONiC as wheel packages rather than Debian packages. This will also allow us to more easily transition to Python 3.
Python files are now packaged in "sonic-utilities" Pyhton wheel. Data files are now packaged in "sonic-utilities-data" Debian package.
**- How I did it**
- Build and install sonic-utilities as a Python package
- Remove explicit installation of wheel dependencies, as these will now get installed implicitly by pip when installing sonic-utilities as a wheel
- Build and install new sonic-utilities-data package to install data files required by sonic-utilities applications
- Update all references to sonic-utilities scripts/entrypoints to either reference the new /usr/local/bin/ location or remove absolute path entirely where applicable

As per the VOQ HLDs, internal networking between the linecards and supervisor is required within a chassis.
Allocating 127.X/16 subnets for private communication within a chassis is a good candidate.
It doesn't require any external IP allocation as well as ensure that the traffic will not leave the chassis.
References:
https://github.com/Azure/SONiC/pull/622https://github.com/Azure/SONiC/pull/639
**- How I did it**
Changed the `interfaces.j2` file to add `127.0.0.1/16` as the `lo` ip address.
Then once the interface is up, the post-up command removes the `127.0.0.1/8` ip address.
The order in which the netmask change is made matters for `127.0.0.1` to be reachable at all times.
**- How to verify it**
```

SNMP and Telemetry services are not critical to switch startup.
They also cause fast-reboot not to meet timing requirements.
In order to delay start those service are associated with systemd
timer units, however when hostcfgd initiate service start, it start
the service and not the timer. This PR fixes this issue by
starting the timer associated with systemd unit.

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 in https://github.com/Azure/sonic-buildimage/pull/5003
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
This is the next step toward resolving https://github.com/Azure/sonic-buildimage/issues/4999
Also reverted my previous change in which device_info.get_platform() would first try obtaining the platform ID string from Config DB and fall back to gathering it from machine.conf upon failure because this function is called by sonic-cfggen before the data is in the DB, in which case, the db_connect() call will hang indefinitely, which was not the behavior I expected. As of now, the function will always reference machine.conf.
* [platform] Add Support For Environment Variable
This PR adds the ability to read environment file from /etc/sonic.
the file contains immutable SONiC config attributes such as platform,
hwsku, version, device_type. The aim is to minimize calls being made
into sonic-cfggen during boot time.

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.
`sonic-installer list` is a read-only command. Specify it as such in the sudoers file.
This will also ensure the new `show boot` command, which calls `sudo sonic-installer list` under the hood doesn't fail due to permissions.

- Why I did it
Add support to specify source address for TACACS+
- How I did it
Add patches for libpam-tacplus and libnss-tacplus. The patches parse the new option 'src_ip' and store the converted addrinfo. Then the addrinfo is used for TACACS+ connection.
Add a attribute 'src_ip' for table "TACPLUS|global" in configDB
Add some code to adapt to the attribute 'src_ip'.
- How to verify it
Config command for source address PR in sonic-utilities
config tacacs src_ip <ip_address>
- Description for the changelog
Add patches to specify source address for the TACACS+ outgoing packets.

* [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.

- Ensure all features (services) are in the configured state when hostcfgd starts
- Better functionalization of code
- Also replace calls to deprecated `has_key()` method in `tacacs_server_handler()` and `tacacs_global_handler()` with `in` keyword.
This PR depends on https://github.com/Azure/sonic-utilities/pull/944, otherwise `config load_minigraph` will fail when trying to restart disabled services.
While migrating to SONiC 20181130, identified a couple of issues:
1. union-mount needs /host/machine.conf parameters for vendor specific checks : however, in case of migration, the /host/machine.conf is extracted from ONIE only in https://github.com/Azure/sonic-buildimage/blob/master/files/image_config/platform/rc.local#L127.
2. Since grub.cfg is updated to have net.ifnames=0 biosdevname=0, 70-persistent-net.rules changes are no longer required.
Don't limit iptables connection tracking to TCP protocol; allow connection tracking for all protocols. This allows services like NTP, which is UDP-based, to receive replies from an NTP server even if the port is blocked, as long as it is in reply to a request sent from the device itself.

I found that with IPv4Network types, calling list(ip_ntwrk.hosts()) is reliable. However, when doing the same with an IPv6Network, I found that the conversion to a list can hang indefinitely. This appears to me to be a bug in the ipaddress.IPv6Network implementation. However, I could not find any other reports on the web.
This patch changes the behavior to call next() on the ip_ntwrk.hosts() generator instead, which returns the IP address of the first host.
Fix hostcfgd so that changes to the "FEATURE" table in ConfigDB are properly handled. Three changes here:
1. Fix indenting such that the handling of each key actually occurs in the for key in status_data.keys(): loop
2. Add calls to sudo systemctl mask and sudo systemctl unmask as appropriate to ensure changes persist across reboots
3. Substitute returns with continues so that even if one service fails, we still try to handle the others
Note that the masking is persistent, even if the configuration is not saved. We may want to consider only calling systemctl enable/disable in hostcfgd when the DB table changes, and only call systemctl mask/unmask upon calling config save.
