SqlSupport refactoring

[dansysanalyst]

Hi Luan,

According to Laravel 8x - Database PowerGrid should be supporting:

• MySQL 5.7+ (Version Policy)
• PostgreSQL 9.6+ (Version Policy)
• SQLite 3.8.8+
• SQL Server 2017+ (Version Policy)

I wrote a test to verify the sortField syntax for database + version. I do not remember if we had an alternative solution for the field+0. For the moment, I left it as default for situations:

All tests passing, could not test Sql Server locally.

Static analysis also OK on the desired level.

@vs0uz4 I have not touched the docker-compose; however, I think it would be best to also downgrade it to make sure tests run in the minimum supported database.

Hopefully, it solves the compatibility problem.

Thanks

Dan, this implementation of driver and version verification is too beautiful, congratulations. And these tests, huh? Wow, you really went all out in PR. Very well approved.
