Thomas Eizinger 1d0ecf94b8 feat(relay): record metrics about bytes relayed via eBPF (#8556) ...

Perf events are designed to be an extremely efficient way of
transferring data from an eBPF kernel to the user-space program. In
order to monitor, how much traffic we are actually relaying via eBPF, we
introduce a dedicated `STATS` map that is a `PerfEventArray`.

The events from that array are read asynchronously in user-space and fed
into our OTEL metrics. They will show up in our Google Cloud metrics as
`data_relayed_ebpf_bytes`. We already have a metric for the total
relayed bytes. That counter is renamed to `data_relayed_userspace_bytes`
so we can clearly differentiate the two.
