Henry Robinson 60cbe1b0e1 IMPALA-741: Support partitions with non-existant HDFS locations ...

If a partition had a location that did not exist in HDFS, Impala would
refuse to load its metadata. This meant a typo could render a table
unloadable. We fix this problem by removing the existence check from the
frontend, and by inheriting access from the first extant parent of the
partition directory.

Fixing this exposed a second issue, where Impala wouldn't create
directories for partitions in the right place after an INSERT if the
partition location had been changed. To get this right we have to plumb
the partition ID through to Coordinator::FinalizeSuccessfulInsert(), so
that the coordinator can look up the partition's location from the
query-wide descriptor table. As a by-product, this patch rationalises
the per-partition, per-fragment statistics gathering a little bit by
putting almost all the per-partition stats into TInsertPartitionStatus.
