Review comment:
IMO, we don't need this mock. Could have just removed `indextableexists` and/or `indexexists` property appropriately from parent table. I mean, can do like below
`parentCarbonTable.getTableInfo.getFactTable.getTableProperties.remove("indextableexists")`
and/or
`parentCarbonTable.getTableInfo.getFactTable.getTableProperties.remove("indexexists")`
appropriately. Probably can check all testcases using `mockIsIndexTableExists()` and `mockIsIndexExists()`.
