    I'm pretty sure, this should have been `FILESYSTEM` and I was just to eager 
to change everything to `ZOOKEEPER` when copying the tests over... Anyway, this 
option is not used at all because we only test the BLOB service classes (also 
in the test classes I copied this from).

> A {{PermanentBlobStore}} should resemble use cases for BLOBs that are 
> permanently stored for a job's life time (HA and non-HA).
> A {{TransientBlobStore}} should reflect BLOB offloading for logs, RPC, etc. 
> which even does not have to be reflected by files.
