Description

Currently, DistributedCacheEntries are written into the ExecutionConfig on the client and later extracted again by the FileCache on the TaskManager.

This approach is more complex and error-prone than necessary, as the map of entries are already serializable, and in fact are already sent to the JobManager.

We can instead simply store the map of entries directly in the TaskDeploymentDescriptor.
