bump Rust Driver to 1.8.0

[wprzytula]

As a result of the bump, some tests from ControlConnectionTests broke, because some log messages changed. The tests are adjusted for the new contents.

Pre-review checklist

• [ ] I have adjusted the documentation in ./docs/source/.
• [ ] I have implemented Rust unit tests for the features/changes introduced.
• [ ] I have enabled appropriate tests in Makefile in {SCYLLA,CASSANDRA}_(NO_VALGRIND_)TEST_FILTER.
