   …tistics call

   this commits add support for table property 
"read.spark.disable-estimate-statistics"
   which will return default value of table statistics and avoid reading 
manifest and data files
   to get table size and row count.
   this feature is useful for spark2 as spark2 does not perform predicate 
pushdown before calling
   estimateStatistics which ends up scanning entire table.
   this feature may be useful for spark3 if table manifest list is large even 
after predicate pushdown.
