7.0.x AutoTmestamp Enhancements + grails.importGrailsAnnotations GrailsExtension

[codeconsole]

Introduce @CreatedDate and @LastModifiedDate similar to Spring Data

Introduce grails.importGrailsAnnotations to automatically import common grails annotations.

build.gradle

grails {
    importJavaTime = true
    importGrailsAnnotations = true
}

allows the following with no imports

class User {
    String firstName
    String lastName
    String email
    @CreatedDate Instant created
    @LastModifiedDate Instant modified
}

@Scaffold(domain = User)
class UserService {}

import grails.plugin.scaffolding.RestfulServiceController

@Scaffold(RestfulServiceController<User>)
class UserController {}

While I understand why you added it while at it, this technically does not have anything to do with time.
It should probably be in a subsequent PR?

[codeconsole]

@sbglasius I agree it could of been in a separate PR, but it's kind of a gray area because the added config is importGrailsAnnotations and that is just adding 1 annotation @Scaffold. Plus there is a lot I want to address and the latency in getting PRs reviewed is a bit slow at the moment for what I want to get added/fixed.

The motivation for this PR is actually for importGrailsAnnotations. I was originally against
@matrei 's suggest of having 2 different annotations for AutoTimestamp because of the extra import statement on every domain class, but with importGrailsAnnotations, I don't mind.

In fact, with importGrailsAnnotations, I am even willing to get rid of @AutoTimestamp now. @matrei what are your thoughts about getting rid of @AutoTimestamp?

Per the weekly meeting, we'll merge this into 7.1. The vote to create that branch is going now - once 72 hrs have passed, we'll create the branch.
