Create a new annotation that bubbles up @Execution, @ExtendWith, and @SpringBootTest

[kgress]

Summary:

We should create a new annotation that allows users implementing scaffold to have just one annotation instead of three on their BaseTest file.

E.G, on an implementing project "AutomationCodeBase" :

@Execution(ExecutionMode.CONCURRENT)
@ExtendWith(SpringExtension.class)
@SpringBootTest(
        webEnvironment = SpringBootTest.WebEnvironment.NONE,
        classes = { AutomationCodeBaseConfig.class, ScaffoldConfig.class }
)
public class BaseTest extends ScaffoldBaseTest { ... }

This is a bit heavy and having a single annotation that bubbles all of these configurations up would be helpful.

A/C:

• Create a new Spring annotation that includes the execution mode, the SpringExtension, and the SpringBootTest configuration annotations

Few things here:

• SpringBootTest already extends from SpringExtension.class. We can remove that from this usage.
• Execution mode shouldn't be forced as concurrent, as there might be some users that need synchronous
• Scaffold configuration can be loaded through the environment's configuration on the implementation with `@ComponentScan(value = "io.github.kgress.scaffold"), in addition to the implementing projects own classpath
• WebEnvironment doesn't need to be specified here

Because of the reasons above, I don't think we need a custom annotation. I've updated documentation for usage.
