create a script which can bootstrap an entire cluster to run out of hdfs

The current bootstrap script syncs the entire tree across the cluster; it would be better for it to pull down a script on each node which will then pull down any resources it needs from hdfs and start up the proper servers.

for h in `cat conf/slaves`
do
  scp conf/accumulo-site.xml $h:
  ssh $h 'hadoop fs -get /accumulo/bin/start-here.sh ; ./start-here-sh accumulo-site.xml'
done
