Thomas Eizinger 941ef6c668 feat(relay): introduce feature-flag for toggling eBPF program (#8650) ...

This PR implements a feature-flag in PostHog that we can use to toggle
the use of the eBPF data plane at runtime. At every tick of the
event-loop, the relay will compare the (cached) configuration of the
eBPF program with the (cached) value of the feature-flag. If they
differ, the flag will be updated and upon the next packet, the eBPF
program will act accordingly.

Feature-flags are re-evaluated every 5 minutes, meaning there is some
delay until this gets applied.

The default value of our all our feature-flags is `false`, meaning if
there is some problem with evaluating them, we'd turn the eBPF data
plane off. Performing routing in userspace is slower but it is a safer
default.

Resolves: #8548
