- What I did
libyang python APIs for handling Yang model schema and data trees

- How I did it

build libyang python debian packages
privode a set of python APIs to handle Yang model schema and data trees:
load yang module files

load yang data files

Yang schema tree
. get yang model object from model name or xpath etc
. get schema tree in xml, json or tree format
. print schema tree
. schema node parent xpath
. schema node xpath

Yang data tree
. load yang data file
. find data node from xpath
. get/set data node value
. add/delete data node
. merge two data trees
. find data dependencies

- How to verify it
pytest:

  • a set of test functions to test all the APIs
  • a test data file contains all the tests to run
  • easy to add more tests in the test data file

- Description for the changelog

- A picture of a cute animal (not mandatory but encouraged)

- specify YANG 1.1 version in sonic-acl.yang for libyang YANG1.1 support
- libyang debian package name format from libyang github

Hi Ping, seems these commits are for libyang. I was expecting sonic_yang and setup.py related code here.
