IMPALA-3040: Remove cache directives if a partition is dropped externally

HdfsTable.dropPartition() doesn't uncache the partition right now. If
the partition is dropped from Hive and refreshed in Impala, the
partition will be removed from the catalog but the cache directive
remains. Because Impala directly uses HMS client to drop a
table/database, the cache directive won't be removed even if the table
is dropped in Impala, if the backgroud loading is run concurrenty with
the HMS client RPC call. This patch removes the cache directive in
dropPartition() to fix this bug.
