Could you also clear unconditionally?

I think there is no unconditional flag clear, maybe a clearFlagForTest method or an ASSERT that the state matches expected?

I think that my comment of "how do we know what hosts to clear?" is outdated. Since the only health flags that get set are those that are degraded and excluded, which will naturally be in that HostVector regardless? Thus making this work?

Commit Message: Scaled Load Balancer Fuzz to 60k hosts.
Additional Description: In order to truly represent the production search space for Load Balancing in regards to upstream hosts, the Load Balancer fuzzer requires at least 10k upstream hosts. This PR scales it up to 60k hosts. It fixes the bottleneck of constructing thousands of hosts each run by statically declaring the host vector. Also, this PR scales my random subset selector to 32 bits in order to randomly represent this search space, as before it was 8 bits and could only represent 256 hosts.
Risk Level: Low
Testing: Regression tests for 60k hosts.
