IMPALA-7003: Deflake erasure coding data loading

Erasure coding data loading is flaky in two ways:
1. HBase sometimes doesn't work because of HBase-19369
2. Nested data loading sometimes fails because the HDFS namenode cannot
   find enough good datanodes.

For problem 1, this patch enables erasure coding only on /test-warehouse
directory. For problem 2, this patch sets
dfs.namenode.redundancy.considerLoad to false, preventing namenode from
excluding heavily-loaded datanodes.
