> Currently we use "ozone.scm.container.size" (5GB default) in various implementations of PipelineProvider and in ContainerManagerImpl#getMatchingContainer when checking if a DN has enough disk space for a container.
> The problem is that if only 6 GB is remaining, this check will return true concurrently for multiple clients. But there's only space for 1 container, leading to container creation failures for all but 1 client. So we should increase this space requirement to a multiple of container size.
