Refactor the Commands naming and not use 'Service' as naming

[medmes]

Description

The services we have follow the DI pattern which is good but they re not in a sense of the Service convention naming. The Create and Scaffold commands are in a sense of orchestrators or bundler of different structs.

AC

• Rename the Create command Service.
• Rename the Scaffold command Service.

Suggestion

For the Command Lines struct orchestrators, better to name them as CreateCommandExecutor or CreateCommandHandler
