Viper has a feature/bug where all YAML config keys are cast
to lowercase (see https://github.com/spf13/viper/issues/260
and https://github.com/spf13/viper/issues/411).
Since we use Viper to load our config values, it doesn't seem
like there's an easy way to preserve case sensitivity for the
access names chosen by users right now. Adding this prompt
should help user experience by clarifying that all access
names must be lowercase.

We want to make tracing to be opt-in.
For now, we will use `tracing.sample` as the toggle config to enable or
disable tracing and default to sample every traces from uplink cli.
If user wants to change the default sampling rate, they can do so by
using the `--tracing.sample` flag to override the default value
