> For every HDDS Volume, track the space usage in open containers. Introduce a
> counter committedBytes in HddsVolume - this counts the remaining space in
> Open containers until they reach max capacity. The counter is incremented (by
> container max capacity) for every container create. And decremented (by chunk
> size) for every chunk write.
> Space tracking for open containers will enable adding a safety check during
> container create.
> If there is not sufficient free space in the volume, the container create
> operation can be failed.
> The scope of this jira is to just add the space tracking for Open Containers.
> Checking for space and failing container create will be introduced in a
> subsequent jira.
