[3.x] Refactor ServiceConfig::class.

[r-kujawa]

What the diff?

This Pull Request primarily consists of updates and changes related to a software component we use to configure settings for various services, ServiceConfig. The significant changes are as follows:

• Change in File Library Imports
  Across multiple files, we updated where ServiceConfig is imported from, changing it from the Fluent subdirectory to the primary Orchestration directory. This would ensure we're all using the latest version of ServiceConfig for our settings.

• Use of Index-based Option Selection
  In the OrchestrateProvider.php file, the method of option selection was changed to use the index of the option rather than its value. This was done to provide a more standardized and error-free way of choosing settings.

• Variables Assignment Update
  The OrchestrateService.php file introduced assignment expressions for improving the way we define and assign values to certain variables like $name and $id.

• Standardization of Settings Retrieval
  Methods for settings retrieval(get method) were used more extensively in files like OrchestrateProvider.php and DatabaseDriver.php, providing a more standardized way to get the selected option's values.

• Creation of New Source Files
  Two new files ServiceConfig.php and ServiceDriver.php were added to the src directory. These files are likely to include the updated configuration options and functionalities we're adopting, creating a better-organized codebase.

• Modification in Test Files
  Multiple testing files were updated to import the new ServiceConfig path. This ensures our test suites are in alignment with the changes made in the codebase.

Overall, these changes bring a shift towards more secure and efficient ways of managing service configurations, contributing to an improved code quality and enhanced application reliability.
