Improve Usage Data Ping

We should track more data, mainly if certain features are enabled or not. Example: We only track LFS objects, not if the feature is enabled. These metrics are therefor bias.

Proposed features to track:

• LFS enabled
• Container registry enabled See https://gitlab.com/gitlab-org/gitlab-ee/blob/master/lib/gitlab/usage_data.rb#L95
