    Made AbstractServer.hostname volatile (#5656)
    
    The Monitor calls `getMetrics` on each server to get
    their information, and `getMetrics` logs an a message
    if the hostname is `0.0.0.0` and returns an empty
    response. Saw these messages in the gc server log, but
    SimpleGarbageCollector sets the hostname immediately
    after starting the Thrift service in `startStatsService`.
