Miscellaneous updates to the copying operation to Impala Cluster: 

- Assign the WRITE and EXECUTE permissions to the DBs' HDFS-directories, in order to be able to create tables on top of them, in the Impala Cluster.
- Make sure the "copydb" function returns early, when it encounters a fatal error, while respecting the "SHOULD_EXIT_WHOLE_SCRIPT_UPON_ERROR" config.
