Release 1.8.0

[yevhenii-nadtochii]

This changeset sets the version to 1.8.0 and updates the corresponding license report files.

---

This release brings numerous fixes, updates to API and performance improvements.

Breaking Changes

• Instead of NodeId, ShardSessionRecord now uses WorkerId to indicate who is currently processing which shard.

  Thus, all shard processing sessions should be completed before the migration.

  Please see [1.x] Make AbstractWorkRegistry respect the current worker of a node #1433 for details.

API Changes

• Made BlackBoxContext implement Closeable (as addition of [1.x] Enable IntegrationBroker dispatch events regardless of registration order of subscribing and publishing BCs #1402).

• BlackBoxContext API has been extended to provide an instance of Client linked to the context under the test.

  It makes possible to use Client in tests, for example:

  BlackBoxContext context = BlackBoxContext.from(...);
  ClientRequest clientRequest = context.client().asGuest();
  
  assertThat(clientRequest.select(ProjectView.class).run())
          .hasSize(0);
  clientRequest.command(createProject()).postAndForget();
  assertThat(clientRequest.select(ProjectView.class).run())
          .hasSize(1);

  Please note, that provided Client would inherit TenantId from BlackBoxContext, but would NOT inherit UserId and ZoneId.

  Check [1.x] Make BlackBoxContext provide a Client linked to the context under the test #1407 for details.

• Made API calls for the conditional settings of ServerEnvironment "lazy".

  Previously, ServerEnvironment provided two kinds of API calls for the conditional settings:

   ServerEnvironment.when(Staging.class)
                    // This call is handy when `myStorageFactory` is already available.
                    .use(myStorageFactory)
  
   ServerEnvironment.when(PreProduction.class)
                    // And this one looks lazy, so that it is only executed when and _if_ requested.
                    .use((env) -> createMySqlStorage())

  However, in fact, there was no "lazy" behavior, which caused numerous workarounds to actually postpone the initialization of environment-specific settings until they start to make sense.

  This release addresses the issue by making the behavior truly "lazy" (see [1.x] Lazy ServerEnvironment.when(..).use(..) #1421).

Fixes

• Enabled IntegrationBroker dispatch events regardless of registration order of subscribing and publishing Bounded Contexts (see [1.x] Enable IntegrationBroker dispatch events regardless of registration order of subscribing and publishing BCs #1402).

• Transformation of an entity's state during Migration has been changed so that the newState completely overwrites the old one within the migration transaction (see [1.x] Perform clear-and-replace when applying entity Migration #1405).

• The internals of IntegrationBroker were made more thread-safe (see [1.x] Make IntegrationBroker safer. Adjust SubscriptionService for standalone event producers. #1423).

• SubscriptionService now properly locates the Bounded Context when subscribing to events produced by standalone producers, such as descendants of AbstractCommandHandler or AbstractEventReactor (see [1.x] Make IntegrationBroker safer. Adjust SubscriptionService for standalone event producers. #1423).

Performance

• Improved Catch-up caching (see [1.x] Improve Catch-up Caching #1406 for details).
