Start the process
Start the process
The method is idempotent. It will not execute start twice. It will also not start the process if close() has already been called. In that case, the returned future fails with com.digitalasset.canton.lifecycle.StartAndCloseable.StartAfterClose. If close is called concurrently, it will delay the close until the start has succeeded.
