The LocalDIrManager class used to allocate disk space for HDFS block storage
and cloud connector buffers should now recover from directory deletion on all
codepaths.
This situation can occur in cloud connectors uses when cron jobs clean up
temp directories on a schedule.
There is also significantly better logging of the allocation process
failures.
