Make services lazy

[WedgeSama]

Description

Some compute are done when services are instantiated (e.g. injected). Better to compute only if the service is really used.

Why did I do that? Multiple reasons:

• Optimize the services creation, less compute if not needed
• Fix cases when you when your app to work (composer install, page rendering, etc...) without having a credentials.json
• Do not change how most of the bundle works

Plus some optimizations:

• ProjectFactory service do not need Factory factory injection (no argument in its constructor).
• ProjectFactory::createFactory if we really want a new instance, use new instead of clone to ensure it.

Checklist:

• My code follows the style guidelines of this project
• I have performed a self-review of my own code
• I have added tests that prove my fix is effective or that my feature works (only update 2 tests to load lazy service)
• I have made corresponding changes to the documentation (does not need any change)
