deps: Explicitly pin netty to 4.1.119.Final to fix R2DBC with MariaDB

[hessjcg]

The MariaDB R2DBC drivers are not compatible with Netty 4.2. We have tried several versions of the Netty library, but none seem to work. This causes integration tests to fail with the error below. This problem is not caught by the current unit test suite.

We are configuring our tools to ignore updates past Netty 4.1.119.Final.

Closing as obsolete. We will use the ./build.sh deps going to update Java dependencies going forward.
