>
> {{StorageContainerManager}}'s block protocol creates a new container for each
> allocate block call instead of using existing open containers. This behavior
> is not seen once the cluster is restarted.
> When {{createContainer}} flag is set, the container state is changed from
> {{ALLOCATED}} to {{CREATING}}. But in {{refreshContainers}} call only
> {{ALLOCATED}} state is handled.
> During restart {{loadAllocatedContainers}} loads the {{containers}} map
> properly, which fixes the issue after restart. But we will face the same
> issue later when we allocate new containers.
