[MikeGoldsmith]

Review hardcoded logsize and whether we should allow users to adjust via configuration.

Copying my comment from the original thread:

The default size is 1024 bytes, which may not be enough for all eBPF programs.
This sets the size of the requested buffer allocated from the kernel when loading eBPF programs. Allowing users to control it may have some security concerns (for example, setting a really high value causing huge memory allocation)

Verifier log size was removed in #965. Upstream removed the need to configure this: https://github.com/cilium/ebpf/releases.
