This PR contains various fixes to make the client compatible with
the 5.2 server.

- Server version used in tests bumped to 5.2.2
- For Compact, field kinds are updated with the up-to-date enum values
and they are moved to the serialization.api from compact, to match
with the Java side
- Dependency on the enterprise-tests JAR is removed and the self-signed
certificates that we depend on moved to the client-side, instead
of adding a dependency to the private test artifacts.
- Some reactor related tests that fail on macOS are fixed
