predicates/host: add HostAny benchmark (#3239)

Current implementation uses linear probe that works well for small number
of hosts.

I thought about implementing it using map lookup but that is slower for
less than 50 hosts so I propose to only keep the benchmark that may be used
for future improvements.

Here is comparison with map-based implementation for reference:
