Michael Smith 8b83726b8e IMPALA-9487: Add erasure coding policy to SHOW, DESCRIBE 
Adds erasure coding policy to introspection commands SHOW FILES, SHOW
PARTITIONS, SHOW TABLE STATS, and DESCRIBE EXTENDED.

Remove `throws IOException` for methods that don't throw. Removes null
check for getSd because getStorageDescriptorInfo - which is called right
after getTableMetaDataInformation - uses it without checking for null.

Adds '$ERASURECODE_POLICY' for runtime test substitution. The test suite
replaces this with the current erasure code policy - from
HDFS_ERASURECODE_POLICY - or NONE to match expected output.

Testing:
- ran backend, end-to-end, and custom cluster tests with erasure coding
- ran backend, end-to-end, and custom cluster tests with exhaustive
  strategy
