refactor: [#1228] remove deprecated unified HTTP and UDP stats

Stats have been split into HTTP and UDP stats.

Parallel change, step 4:

1. [x] Start using HTTP Tracker Core Stats
2. [x] Start using UDP  Tracker Core Stats
3. [x] Get metrics from HTTP and UDP Tracker Core Stats
4. [x] Remove deprecated unified HTTP and UDP stats.
