Restructure usage ping | Add Usage Activity to CE

Overview

The current usage_ping.rb files have a complicated structure where:

1. Counters are split across two files (Core and EE)
2. SMAU counters only exist in EE

This structure makes it difficult for a developer to understand where to put their code if they are modifying or adding usage pings.

Next Steps

• Move all stage counters to CE file
• Run Usage Ping on CE, see the -1 failures to identify which counters are in CE vs EE.
• Move broken counters back to EE file
• Verify this is working on GitLab.com
• Verify this is working on CE
• Ask stage PMs to verify
