Add container level to config tool

[cemms1]

What's changed?

Uses latest release of facia-scala-client which adds SecondaryLevel as a possible metadata value.

The previous implementation had both Primary and Secondary as metadata options but since all containers are considered "primary" unless specified as "secondary", we can reduce this to just one option. This also includes the word "level" as part of the metadata to better communicate what this does and how it is distinct from a palette option.

This PR also applies special styling to secondary level containers at the fronts tool level by reducing the size of the container title and using sans font family, much like the way the platforms will treat secondary level containers.
