Generic implementation of InsertIntoTable function from testing/commons.*

The current implementation assumes that the schema of the table follows *StdRow*. There can be a few enhancements to the implementation:
1) Currently *StdRow* is implemented using `std::vector`. This can be changed to `std::tuple`, which will make the data to be inserted more type safe.
2) Since a tuple cannot be traversed through a for loop, we may need to implement the function as a template. We can assume a limit on the number of columns.
