Threat Shield: warnings when loading ip blacklists

[mrmarkuz (Markus Neuberger)]

It’s a hardcoded limit:

Threat shield: Hash is full, cannot add more elements

Each set can actually have max 131072 elements: https://github.com/NethServer/nethserver-blacklist/blob/master/root/usr/share/nethserver-blacklist/load-ipsets#L111 For now the limit is hard-coded. Extending such limit, could eventually bring to performance loss. Also bear in mind that many ipsets has duplicated IPs. I think that you did the right choice: do not use extremely large ipsets.
