Review comment:
Yes - this is that whole can of worms fixed in ZOOKEEPER-2901. The max
ServerId is determined by whether or not TTL nodes are enabled via
`zookeeper.extendedTypesEnabled` - the docs now stipulate: `IMPORTANT: if you
enable extended features such as TTL Nodes ... the id must be between 1 and 254
due to internal limitations.`
