- Increase the global level for broadcaster's logging to 3 so that users can ignore event messages by lowering the logging level. It reduces information noise.
- Making sure the context is properly injected into the broadcaster, this will allow the -v flag value to be used also in that broadcaster, rather than the above global value.
- test: use cancellation from ktesting
- golangci-hints: checked error return value
Since ServiceCIDR and IPAddresses are mostly API driven integration
test will give us a good coverage, exercising real use cases like
the migration from one ServiceCIDR range to a new range.
