Flag --incompatible_config_setting_private_default_visibility will break Cloud Robotics Core in Bazel 7.0

[keertk]

Incompatible flag --incompatible_config_setting_private_default_visibility will be enabled by default in the next major release (Bazel 7.0), thus breaking Cloud Robotics Core. Please migrate to fix this and unblock the flip of this flag.

The flag is documented here: bazelbuild/bazel#12933.

Please check the following CI builds for build and test results:

• Ubuntu 18.04, OpenJDK 11

Never heard of incompatible flags before? We have documentation that explains everything.
If you have any questions, please file an issue in https://github.com/bazelbuild/continuous-integration.
