    Stop GC and SServers first when stopping cluster (#5396)
    
    * Stop GC and SServers first when stopping cluster
    
    The GC and Scan Server processes can put a load onto the
    metadata table with scan and writes. This activity could
    hold up metadata tablet unloading. These processes aren't
    necessary for an orderly shutdown, so they can be shut
    down first.
    
    * Removed duplicate local declarations
