Is it possible not to assume the installation path? I know it may be tricky to import a script.

Got rid of load_source altogether.

Do not catch general exception type unless you have a good reason.

Exception [](start = 18, length = 9)
Not to throw general exception type. This looks a normal logic, not like a literal 'exception'. How about using return value?

Was not able to include in install_requires: tried sonic_cfggen and sonic-cfggen.
Also when checking the code behind show runningconfiguration all it is implemeted as:
@runningconfiguration.command()
@click.option('--verbose', is_flag=True, help="Enable verbose output")
def all(verbose):
"""Show full running configuration"""
cmd = "sonic-cfggen -d --print-data"
run_command(cmd, display_cmd=verbose)Which means they just depend on the system to have, and we here are doing the same.
We can either leave it as as, or just rely on the command from cli

The name is sonic-config-engine. Currently it is tests_require. We should remove it, and add as install_requires.

docker-sonic-vs is downloaded then the new sonic-utilities package is installed with most recent modifications. Problem happens if the new package has new external libs or one of the libs is updated as using the command pip3 install with --deps just leave the deps unchanged.
I tried different ideas:
pip3 install /wheels/sonic_utilities-1.2-py3-none-any.whl
does not do anything because the package is already installed in the docker-sonic-vs
pip3 install --force-reinstall /wheels/sonic_utilities-1.2-py3-none-any.whl
does not work because it also forces the deps to be updated but some of the deps such as sonic-py-common are not available in public pip repo and are installed with the sonic image in docker-sonic-vs
pip3 install --update /wheels/sonic_utilities-1.2-py3-none-any.whl
does not update sonic-utilities package and only updates its dependencies
The proposed soln achieved the following:
- Force install sonic-utilities package
- Adding missing dependencies
- Upgrading out-dated dependencies
- Leaving dependencies provided by the sonic-build process unchanged.

This option is added to make the code ready to use SonicYang format in the future once our internal services start interacting with SONiC boxes using SonicYang. Do you suggest we add it to the design document, remove it from here, or leave it as is?

Better to update the design doc.

A patch is a JsonPatch which follows rfc6902. This command can be used do partial updates to the config with minimum disruption to running processes. It allows addition as well as deletion of configs. The patch file represents a diff of ConfigDb(ABNF) format or SonicYang format. <patch-file-path>: Path to the patch file on the file-system.

What I did
Adding apply-patch, rollback, replace, checkpoint, delete-checkpoint, list-checkpoints functionality.
How I did it
This PR is implementing the first step in in README.md in the design document: sonic-net/SONiC#736
How to verify it
Using unit-tests
Previous command output (if the output of a command-line utility has changed)
New command output (if the output of a command-line utility has changed)
