Remove the feature ids from the Features roadmap report Merged

We would like  to customize further the product timeline view of the reports by removing the feature ids from the roadmap. 

At the moment the product timeline view shows for each feature the feature ID prior to the summary of the feature. This prevents us to share this report externally with our customers. 

Without these IDs we would just have the product versions with a list of features and that's something that we could copy paste in a power point and show to customers. But with internal IDs it looks like an internal roadmap rather than a customer-facing roadmap.
