Asynchronous Account Creation with CompletableFuture in Java

This code creates multiple CompletableFuture objects to perform account creation tasks asynchronously. It iterates through a list of account names, extracts the role name and tenant name from each account name, and creates two CompletableFuture objects for each account: one for creating a machine account and one for creating a person account.

The CompletableFuture objects for creating roles and tenants are also created and used as dependencies for the machine and person account creation tasks.

All CompletableFuture objects are added to a list, and the list is passed to CompletableFuture.allOf() to wait for all tasks to complete before proceeding to 'sendMessage()' and 'updateAccountInfo()' methods.

Overall, this code efficiently uses CompletableFuture objects to perform multiple tasks asynchronously and in parallel.
