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.
virtual-chassis test uses multiple vs instances to simulate a
modular switch and a redis-chassis service is required to run on
the vs instance that represents a supervisor card.
This change allows vs docker start redis-chassis service according
to external config file.
**- Why I did it**
To support virtual-chassis setup, so that we can test distributed forwarding feature in virtual sonic environment, see `Distributed forwarding in a VOQ architecture HLD` pull request at https://github.com/Azure/SONiC/pull/622
**- How I did it**
The sonic-vs start.sh is enhanced to start new redis_chassis service if external chassis config file found. The config file doesn't exist in current vs environment, start.sh will behave like before.
**- How to verify it**
The swss/test still pass. The chassis_db service is verified in virtual-chassis topology and tests which are in following PRs.

Added required packages to enabled YANG dependency check for Dynamic Port Breakout in VS container.
[sonic-utilities PR #766](https://github.com/Azure/sonic-utilities/pull/766) has a dependency on it.
Getting error like the following without this fix: `ImportError: No module named yang - required module not found`

* [build]: put stretch debian packages under target/debs/stretch/
* in stretch build phase, all debian packages built in that stage are placed under target/debs/stretch directory.
* for python-based debian packages, since they are really the same for jessie and stretch, they are placed under target/python-debs directory.
