[CARBONDATA-221] Fix the bug of inverted index that store inverted index in metadata.
## Why raise this pr?
1. Problem: In current code, inverted index in ddl info is not stored into store, and when we restart the cluster, query might mismatch.
2. To fix problem 1, current code set always true to use inverted index, and we can not configure inverted index now, this is not reasonable. We should fix this problem from its root cause.
## How to solve?
Using the Encoding as the indentifier to check whether using inverted index, this Encoding is in thrift format now, so we no need to modify the thrift format.
## How to test?
Pass all the test cases.

[CARBONDATA-221] Fix the bug of inverted index that store inverted index in metadata by using Encoding.INVERTED_INDEX.
## Why raise this pr?
1. Problem: In current code, inverted index in ddl info is not stored into store, and when we restart the cluster, query might mismatch.
2. To fix problem 1, current code set always true to use inverted index, and we can not configure inverted index now. We should fix this problem from its root cause.
## How to solve?
Using the Encoding as the indentifier to check whether using inverted index, this Encoding is in thrift format now, so we no need to modify the thrift format.
Here it is the same to the query logic in CompressedDimensionChunkFileBasedReader:
```
if (CarbonUtil.hasEncoding(dimensionColumnChunk.get(blockIndex).getEncodingList(),
Encoding.INVERTED_INDEX)) {
invertedIndexes = CarbonUtil
.getUnCompressColumnIndex(dimensionColumnChunk.get(blockIndex).getRowIdPageLength(),
fileReader.readByteArray(filePath,
dimensionColumnChunk.get(blockIndex).getRowIdPageOffset(),
dimensionColumnChunk.get(blockIndex).getRowIdPageLength()), numberComressor);
// get the reverse index
invertedIndexesReverse = getInvertedReverseIndex(invertedIndexes);
}
```
it also use Encoding.INVERTED_INDEX to check whether one column is use inverted index.
## How to test?
Pass all the test cases.
