Turn into a cookiecutter template

[jorgepiloto]

This PR solves for #1. Several tasks need to be completed before this can be merged:

• Use pytest-cookies for template testing.
• Use tox for pkg testing, following Switch to using Tox to control pipelines/environments template#7.
• Setup GitHub actions for checking code quality, tests and integrity of baked template.
• Use poetry group dependencies as dev-dependencies will be deprecated.
• Use pre-commit for in baked project.

---

PR Follow-up

• Update the documentation at https://github.com/pyansys/dev-guide and provide directions regarding template usage.
• Add a note within https://github.com/pyansys/template to indicate it's deprecated and to use this repo instead.

At first, I was considering using cookiecutter private variables in order to sanitize inputs from the user. Although private variables are available in cookiecutter==1.7.3, they do not render properly, see issue cookiecutter/cookiecutter#1461. Furthermore, latest releases of cookiecutter have been published only in PyPI test, forcing users to run:

python -m pip install python -m pip install https://github.com/cookiecutter/cookiecutter/archive/refs/tags/2.0.2.tar.gz

By the way, previous installation ships with wrong metadata, saying that installed version is 2.0.0 instead of 2.0.2... Having encountered all these issues, I decided to use cookiecutter==1.7.3 an wait till issue cookiecutter/cookiecutter#1636 is solved.

Preparing tox, GitHub actions and tests to speed up this using TDD.

Although the actions are setup, I see that the style checks are being running in implicit form inside the py37 jobs. Let me try to make those explicit so that the resulting actions look like:

- Code style
- Baking tests [all matrix.os and matrix.python-version]

[jorgepiloto]

Cool, now code style is a separate job in the CI pipelines and is not executed twice in py37 testing environments.

Following the culture from other projects in the organization, let me also include the pre-commit tool 👍

While trying to add a check for the poetry install baked_project --with group0,group1,... I ran into the following issue python-poetry/poetry#4842. It is not a big deal anyway, but hose repeated optional = true flags are a little bit annoying.

Just before merging:

• Documenting how to use this template in README.md.
• Document baked project README.md according to build-system.
• Check dependabot.

[jorgepiloto]

Finally, this is ready for review, @akaszynski.

We covered all the currently available building systems and tested those in deep (when possible). During the next days, we should expect feedback in the form of issues, enhancements or even bugs.

Merging this! I did not squashed commits so we can properly point to outdated failing actions in order to report issues to third party libraries.
