Multiple tasks of the same job run in a TaskManager. This means that tasks
delete each others blobs.

> Project: Flink
> Issue Type: Improvement
> Components: Network
> Affects Versions: 1.3.0
> Reporter: Nico Kruber
> Assignee: Nico Kruber
>
> The following things should be improved around the BlobServer/BlobCache:
> * update config uptions with non-deprecated ones, e.g.
> {{high-availability.cluster-id}} and {{high-availability.storageDir}}
> * promote {{BlobStore#deleteAll(JobID)}} to the {{BlobService}}
> * extend the {{BlobService}} to work with {{NAME_ADDRESSABLE}} blobs
> (prepares FLINK-4399]
> * remove {{NAME_ADDRESSABLE}} blobs after job/task termination
> * do not fail the {{BlobServer}} when a delete operation fails
> * code style, like using {{Preconditions.checkArgument}}
