> Host replacements require host ID and token, however reporting of this info 
> is typically blocked when the “status” field is missing. We should expose a 
> system env (-D) param to advanced operators to have the ability to specify 
> the replace_addresses_token to be used during host replacement in cases where 
> Gossip gets into a bad state.
> Given this is inherently an unsafe / high risk manual intervention, we want 
> to avoid promoting this to being a config param however Gossip quite often 
> contorts into problematic split-brain states like this and having the ability 
> to manually override things helps unstick host replacements that go 
> straddled. Should update NEWS.txt at the very least and consider 
> documentation as well
> This is an interim solution that'll be obviated by CEP-21, but is still 
> useful on existing clusters.
