Review request for accumulo.


Bugs: ACCUMULO-2005
    https://issues.apache.org/jira/browse/ACCUMULO-2005


Repository: accumulo


Description
-------

ACCUMULO-2005:  Add a 3rd argument to functional test's RunTests.java to take in as input
a scaling factor for 'mapred.task.timeout'.   This will allow functional tests running as
MR job to complete with the right value for 'mapred.task.timeout' instead of failing.   This
scaling factor, called 'timeout_factor', is an integer indicating multiples of the default
value of 480 secs for 'mapred.task.timeout'.   For instances, a timeout_factor of 1 means
480 secs, and 2 would be 960 secs, and so on.

Testing was done on small cluster (4 nodes: master + 3 workers) to ensure MR job complete
successfully instead of failing out due to timeouts that lead to killed attempts.
