This reverts commit 8b41bf4.
There are cases when Netty's DNS resolver may put an exception into the cache and return it multiple times. In this case, we keep adding suppressed exceptions to the same instance and it leads to a memory leak and increased logging output.
Let's revert this feature before the upcoming release and revisit later when we figure out the approach for Netty/ST DNS resolver.
