IMPALA-5042: Use a HashSet instead of ArrayList for O(1) look ups

Testing: Ran the metadata perf benchmark. No regressions and
found good gains in the following cases.

100K-PARTITIONS-1M-FILES-CUSTOM-05-QUERY-AFTER-INVALIDATE ~81.3%
100K-PARTITIONS-1M-FILES-CUSTOM-07-REFRESH ~81.3%
100K-PARTITIONS-1M-FILES-CUSTOM-10-REFRESH-AFTER-ADD-PARTITION ~81.7
