Use any() for tracking updates of schema

In the ticket (IGNITE-15409), configuration began to provide API where any unknown part of configuration key can be replaced to any() function. It is convenient when subscribing of any nested sub-configuration, although the specific root has not created yet.

This API makes sense for subscribing of schemas for table. Look at the comments in the code:

// TODO: IGNITE-15409 Listener with any placeholder should be used instead.
((ExtendedTableConfiguration) tablesCfg.tables().get(tblName)).schemas()
.listenElements(new ConfigurationNamedListListener<>() {
  @Override
  public @NotNull CompletableFuture<?> onCreate(@NotNull ConfigurationNotificationEvent<SchemaView> schemasCtx) {...}
}

Need to rewrite the code in order to use `any()` and remove the comment.
