Jiayu Shen updated CARBONDATA-4051:
-----------------------------------
    Description:
The requirement is from SEQ，related algorithms are provided by group Discovery.

1. Replace geohash encoded algorithm, and reduce required properties of CREATE TABLE. For example,
{code:java}
CREATE TABLE geoTable(
 timevalue BIGINT,
 longitude LONG,
 latitude LONG) COMMENT "This is a GeoTable"
 STORED AS carbondata
 TBLPROPERTIES ($customProperties 'SPATIAL_INDEX'='mygeohash',
 'SPATIAL_INDEX.mygeohash.type'='geohash',
 'SPATIAL_INDEX.mygeohash.sourcecolumns'='longitude, latitude',
 'SPATIAL_INDEX.mygeohash.originLatitude'='39.832277',
 'SPATIAL_INDEX.mygeohash.gridSize'='50',
 'SPATIAL_INDEX.mygeohash.conversionRatio'='1000000'){code}
2. Add geo query UDFs

query filter UDFs :
 * _*InPolygonList (List<String> polygonList, OperationType opType)*_
 * _*InPolylineList (List<String> polylineList, Float bufferInMeter)*_
 * _*InPolygonRangeList (List<Long []> RangeList, **OperationType opType**)*_

*operation only support :*
 * *"OR", means calculating union of two polygons*
 * *"AND", means calculating intersection of two polygons*

geo util UDFs :
 * _*GeoIdToGridXy(Long geoId) :* *Pair<Integer, Integer>*_
 * _*LatLngToGeoId(**Long* *latitude, Long* *longitude) : Long*_
 * _*GeoIdToLatLng(Long geoId) : Pair<Double, Double>*_
 * _*ToUpperLayerGeoId(Long geoId) : Long*_
 * _*ToRangeList (String polygon) : List<Long []>*_

3. Currently GeoID is a column created internally for spatial tables, this PR will support GeoID column to be customized during LOAD/INSERT INTO. For example, 
{code:java}
INSERT INTO geoTable SELECT 0,1575428400000,116285807,40084087;

It uesed to be as below, '855280799612' is generated internally,
+------------+-------------+---------+--------+
|mygeohash  |timevalue   |longitude|latitude|
+------------+-------------+---------+--------+
|855280799612|1575428400000|116285807|40084087|
+------------+-------------+---------+--------+
but now is
+------------+-------------+---------+--------+
|mygeohash  |timevalue  |longitude|latitude|
+------------+-------------+---------+--------+
|0           |1575428400000|116285807|40084087|
+------------+-------------+---------+--------+{code}
