Code Quality (#10)

* `setup.py` is replaced with the `pyproject.toml`. More here: https://peps.python.org/pep-0621/
    * Code Quality tool configurations are improved
    * Dependencies are grouped to be reused by other tools
* All issues are resolved according to code quality requirements
* The `tox` tool is added to the dependencies list to automate the code quality-checking process
    * Python versions that are tested: 3.8, 3.9, 3.10, 3.11, 3.12
    * The `tox.ini` configuration file is created
* Github Actions CI workflow is added
    * Integration tests are not added to the automation process. sLLM service in GithubActions TBD...
* `flake8` linter is removed since the `ruff` is used
* `README.md` now includes the *Code Quality* section with all the instructions and examples

+# Code Quality
+
+The variety of tools are available for checking the code quality.
+
+All the code quality tools configuration is placed into next files: `pyproject.toml`, `Makefile`, `tox.ini`
+
+**To provide the code quality next tools are used:**
+
+- `pytest` as a testing framework
+- `ruff` as a linter
+- `black` & `isort` as formatters
+- `mypy` as a static type checker
+- `tox` as a automation tool
+- `make` as a automation tool (works only on Unix by default)
+
+**Checking code quality using CLI**
+
+All the tools could be run right from the CLI.
+
+Recommended command template: `python -m pytest test.integration`
+
+
+**Checking code quality using Makefile**
+
+Using `Makefile` you can run almost all common scripts to check the code quality, install dependencies, and to provide auto fixes. All the commands from the `Makefile` are valid to be used in the CLI.
+
+Here are some commands
+
+```sh
+# install dev dependencies
+make install.dev
+
+# run unit tests
+make test.unit
+
+# run quality checkers
+make quality
+
+# run autofixes
+make style
+```
+
+**Checking code quality using tox**
+
+The `tox` is an automation tool for running code quality checkers for selected Python versions. The configuration is placed in the `tox.ini`.
+
+To run the automation just run: `python -m tox`
