fix: ensuring consumer-group scoped plugins show tags

On running deck file render command, tags were
coming up for global and service/route scoped
plugins. However, for consumer-group scoped
plugins, the tags did not populate. This was because
the underlying struct did not have tags in the first
place.

This change updates the underlying struct for
consumer-group plugins by adding tags to them
as well. This will ensure that tags show up
during deck file render.
