Support for YugabyteDB's YCQL layer

Based on some simple tests it seems like this is mostly there using the V4 protocol, the only thing missing appears to be handling of its JSONB column type.

As such, would it be feasible to add testing against it to CI and handling for this additional native type?

@Th3-M4jor yes adding that to CI would totally be feasible. As for the native type, I assume it's not documented in the v4 native protocol from C* right? Also, I wont have time to work on this, so I'd be supporting but you'd have to put in the PRs 😄
