Why I did it
This PR adds changes in sonic-config-engine to consume configuration data in SONiC Yang schema and generate config_db entries
How I did it
Add a new file sonic_yang_cfg_generator .
This file has the functions to
parse yang data json and convert them in config_db json format.
Validate the converted config_db entries to make sure all the dependencies and constraints are met.
Add a new option -Y to the sonic-cfggen command for this purpose
Add unit tests
This capability is support only in sonic-config-engine Python3 package only
* [yang-models]: Remove PLY Extensions and change translation code.
With assumption that TABLE_SEPARATOR and ENTRY_SEPARATOR for configDB is always "|",
translation from configDB.json to sonicYang.json can be done based on keys specified
in YANG Lists inside YANG models. So removing extensions is good idea.
Changes:
-- Remove use of regex in Translation code.
-- Remove regex Extensions from YANG models.
-- Improved debugging i.e. log on stdout in case of any Exception from sonic-yang-mgmt,
so that failed tests can be debugged faster. Also this is good to debug Dynamic
port breakout issues.
-- Minor Test changes.

Changes:
— Remove unnecessary file libyang-python-tests/sample_config_db.json
— Keep only config in format of sonic_yang.json in yang_model_tests/yangTest.json.
— Keep config in format of config_db.json in file tests/files/sample_config_db.json
— Add a test case to validate yang models.
**- Why I did it**
As per discussion in sonic Yang workgroup, arranging files better so that Yang model can be in force for new config, also adding a test case to validate young models upto some extent.

**- What I did**
#### wheel package Makefiles
- wheel package Makefiles for sonic-yang-mgmt package.
#### libyang Python APIs:
- python APIs based on libyang
- functions to load/merge yang models and Yang data files
- function to validate data trees based on Yang models
- functions to merge yang data files/trees
- add/set/delete node in schema and data trees
- find data/schema nodes from xpath from the Yang data/schema tree in memory
- find dependencies
- dump the data tree in json/xml
#### Extension of libyang Python APIs:
-- Cropping input config based on Yang Model.
-- Translate input config based on Yang Model.
-- rev Translate input config based on Yang Model.
-- Find xpath of port, portleaf and a yang list.
-- Find if node is key of a list while deletion if yes, then delete the parent.
