    [CARBONDATA-938] Prune partitions for filter query on partition column

    1. generate partition filter by basing on pushed-down filter
    
    2. apply partition filter to get the map of required partition (use BitSet)
    support EqualTo, In, GreaterThan/EqualTo(>, >=), LessThan/EqualTo(<, <=)
    
    3. in CarbonInputFormat, use partition map to skip some non-required splits
    
    4. add query test case
