EPIC - CI: Update & Run all CPP integration tests

[roydahan]

We would like the cpp-rust-driver to have all the original cpp driver tests running as part of CI. This is an umbrella issue (epic) to include all the current & future tasks to get a working running CI and update here about the status of it. (e.g. How many tests we have that are not passing (if any)).

### Tasks
- [ ] Make sure we have all tests from original cpp driver (let's write here the amount of tests)
- [ ] Enable (if not already) all tests to run as part of CI --> how many failing compared to original driver
- [ ] Start openning issues for failing tests / classes / missing functionality

IIRC, some Datastax tests require some functionality besides the API defined by cassandra.h, whereas cpp-rust-driver only supports that API. Can you confirm that @Lorak-mmk?

[Lorak-mmk]

There is additional testing API https://github.com/scylladb/cpp-driver/blob/master/src/testing.hpp https://github.com/scylladb/cpp-driver/blob/master/src/testing.cpp

but it should not be a problem - we can implement it or change the tests to avoid using it (or modify it).

Regarding the issue: We already run integration tests, with both Scylla and C* - or at least the subset that works. You can find the list of used tests in CI yaml: https://github.com/scylladb/cpp-rust-driver/blob/master/.github/workflows/cassandra.yml

Yes, I know we run some. First, we would like to run all and get a mapping of the amount of tests failing compared to original cpp driver and start mapping also missing functionality.

In this epic, we will collect the task items to enable/disable relevant tests and track the status till we reach parity.
