HBASE-19148 Reevaluate default values of configurations 

Removed unused:
    <name>hbase.fs.tmp.dir</name>
Added hbase.master.loadbalance.bytable

Edit of description text. Moved stuff around  to put configs beside each
other.

M hbase-server/src/main/java/org/apache/hadoop/hbase/util/ServerCommandLine.java

 Emit some hbase configs in log on startup.
