Let jhipster generate EntityAuditEvent.

[mshima]

Currently EntityAuditEvent is implemented using jpa/hibernate specific features with angular support only.
By letting jhipster generate we could support:

• others databases
• reactive
• react/vue (list and view)
• microservice support
• microfrontend support

Since it is a generated entity, it will support every feature.

jdl model (won't be used, just as example, we should just inject the Entity definition):

@ReadOnly
entity EntityAuditEvent {
    entityId String required
    entityType String required maxlength(255)
    action EntityAuditAction required maxlength(20)
    entityValue String
    commitVersion Long
    modifiedBy String maxlength(100)
    modifiedDate Instant required
}

enum EntityAuditAction {
    CREATE,
    UPDATE,
    DELETE,
}
