[CARBONDATA-3054] Fix Dictionary file cannot be read in S3a with CarbonDictionaryDecoder.doConsume() codeGen

problem: In S3a environment, when queried the data which has dictionary
files, Dictionary file cannot be read in S3a with CarbonDictionaryDecoder.doConsume() codeGen even though file is present.

cause: CarbonDictionaryDecoder.doConsume() codeGen doesn't set hadoop conf in thread local variable, only doExecute() sets it.
Hence, when getDictionaryWrapper() called from doConsume() codeGen, AbstractDictionaryCache.getDictionaryMetaCarbonFile() returns false for fileExists() operation.

solution:
In CarbonDictionaryDecoder.doConsume() codeGen, set hadoop conf in thread local variable

This closes #2876
