Jihong MA updated CARBONDATA-607:
---------------------------------
    Description: 
Rewrite ValueCompressionHolder class as a base class for compressing or uncompressing numeric
data for measurement column chunk. 

refactor all sub-classes under
org.apache.carbondata.core.datastorage.store.compression.decimal.*
org.apache.carbondata.core.datastorage.store.compression.nonDecimal.*
org.apache.carbondata.core.datastorage.store.compression.none.*
org.apache.carbondata.core.datastorage.store.compression.type.*

as part of the work, also fix a performance bug to avoid creating unnecessary compression/uncompression
value holder during compression or decompression.
