#### Why I did it
Adding exceptlionList to validation exception
#### How I did it
Check code.
#### How to verify it
Ran manually.
- Run full config validation from a KVM
- Print the thrown exception
**Before**
```
Error: Data Loading Failed
All Keys are not parsed in FEATURE
dict_keys(['telemetry'])
```
**After**
```
Error: Data Loading Failed
All Keys are not parsed in FEATURE
dict_keys(['telemetry'])

is defined

Why I did it
Fix#9746
How I did it
Split the check condition based on non-exist and zero length.
How to verify it
Run verification script when table contains empty value
#### Why I did it
If the grouping is in the same file in the module, fetching the grouping fails
#### How I did it
fixing the `uses_module_name` when the grouping is under the same file
#### How to verify it
Enabled a grouping under the same file which is `lldp`, there is a test in sonic-yang-mgmt that translates `sample-config-db` into yang format. This test passes with grouping in `lldp` used.

#### Why I did it
Fixes https://github.com/Azure/sonic-utilities/issues/1871
From [generic-config-updater](https://github.com/Azure/sonic-utilities/tree/master/generic_config_updater) we call `sonic-yang-mgmt` multiple times in order to check a certain change to ConfigDb is valid or not. It is expected for some changes to be invalid, so always printing errors from `sonic-yang-mgmt` makes the output hard to read.
In this PR, we are adding a way to control if logs should be printed or not.
#### How I did it
- Added `print_log_enabled` flag to sonic_yang ctor
- Converted all `print` statements to `sysLog(..., doPrint=True)`
#### How to verify it
unit-test passing means the change did not break logs.
#### Info about libyang logging
libyang provides an extensive logging logic which can support a lot of scenarios:
- ly_log_level: setting logging level
- LY_LLERR
- LY_LLWRN
- ...
- ly_set_log_clb: setting log callback to customize the default behavior which is printing the msgs
- ly_log_options: setting logging options
- LY_LOLOG: If callback is set use it, otherwise just print. If flag is not set, do nothing.
- ...
For more info refer to:
- https://netopeer.liberouter.org/doc/libyang/devel/html/group__logopts.html#gaff80501597ed76344a679be2b90a1d0a
- https://netopeer.liberouter.org/doc/libyang/devel/html/group__log.html#gac88b78694dfe9efe0450a69603f7eceb
#### What's next?
Consume the new flag `print_log_enabled` in [generic-config-updater](https://github.com/Azure/sonic-utilities/tree/master/generic_config_updater) to reduce the logging clutter.

Why I did it
Add YANG model support for table CABLE_LENGTH
How I did it
Add the YANG model file
Add the test description file and config file
add list CABLE_LENGTH_LIST to the qos_maps_model list in sonic-yang-ext, as it has an inner list.
How to verify it
Build sonic-yang-model and sonic-yang-mgmt
Previously the Yang model unit tests pulled directly from the Yang model source code for their models. This worked up to a point where we had jinja templates which needed to be rendered before they could be tested on. Now we need to reference the install location of the rendered templates for the unit tests.
Additionally, PBH yang was never added to the list of models to install onto a switch so I have resolved that (another example why pulling directly from the source was not correct)
My best explanation for why we only saw this failing on mellanox was that these tests could not have possibly been running on the broadcom build (I have not investigated this specifically). There was no way for these tests to pass recently given they were referencing Yang models which did not exist in the source (ACL).
Changes:
-- pre Process Grouping section from all yang models, so it can be used
from any yang model.
-- add jsondiff in setup.py, it is useful for test debugging in case of
failures.
-- use 'stypes' instead of head.
-- pass config DB table name in _createLeafDict().
-- added test config for grouping.
-- white spaces changes.
Note: Changes are done in the way that we can add support for other
Generic YANG statement easily for translation.

Why I did it
SONiC YANG model support for BGP & route-map features.
How I did it
Defined various BGP and route-map YANG containers and lists based on config-DB schema.
How to verify it
Built the following successfully with various BGP & route-map unit test cases.
make target/python-wheels/sonic_yang_models-1.0-py3-none-any.whl
make target/python-wheels/sonic_yang_mgmt-1.0-py3-none-any.whl
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.

Changes:
1.) yang models for device_metadata, device_neighbor, flex_counters, crm, versions.
2.) Test cases for above yang models.

- Add .gitignore files in each subdirectory of src/, so as to reduce the size of the .gitignore file in the project root, and also make it easier to maintain (i.e., if a directory in src/ is removed, there will not be outdated entries in the root .gitignore file.
- Also add missing .gitignore entries and remove outdated entries and duplicates.
Changes:
-- Removing the part where build dependencies are installed in setup.py.
-- Adding build dependencies in corresponsing rules\..*.mk file.
