[SPARK-12938][SQL] DataFrame API for Bloom filter
This PR integrates Bloom filter from spark-sketch into DataFrame. This
version resorts to RDD.aggregate for building the filter. A more performant
UDAF version can be built in future follow-up PRs.
This PR also add 2 specify `put` version(`putBinary` and `putLong`) into
`BloomFilter`, which makes it easier to build a Bloom filter over a `DataFrame`.
