Currently, in database_operation.h, we define operations that can be overridden in each test.

However, one might create a test that does not require read/insert/populate operations but something else, like gathering statistics or log traces, etc. Instead of hard coding the name of each operation that can be overridden, we should give them a generic name.

This change could be straightforward as simply changing the names of those functions. But it would be great to explore other solutions. What if one needs to have 10 operations to run in parallel in their test and database_operation only offers less than 10?
