Consider removing guava dependency

guava is a large dependency but as far as I can tell it is only used in a handful of places:

https://github.com/search?q=repo%3AClickHouse%2Fclickhouse-java+com.google.common&type=code

Start with the linked repository code search for com.google.common and identify every remaining Guava usage. Review those call sites and the dependency configuration, then run the relevant project tests after evaluating whether the usages can be removed or replaced. Done means Guava is no longer required and the test suite still passes.
