    [SPARK-4449][Core] Specify port range in spark

    Based on https://github.com/apache/spark/pull/3314, use a range for port 
retry per @sowen @tgravescs 's comments.
    
    With lots of signature of function changed, user can set "spark.*.port" to 
a string like "a:b" in which "a" represents the minimum port services will 
start on and "b" the maximum.
    
    In the meantime it still gurantee the backward-compatibility which means 
user can still use a single number as ports' value.
