don't put the counter names here, let's use a map and pass it the hook

bq. Summary
bq. -------
bq.
bq. I added the counters mentioned in the task to the MapRedStats class, and
modified HadoopJobExecHelper to collect them.
bq.
bq. I got tired of writing the same code over and over again, so I modified
the way MapRedStats and HadoopJobExecHelper treat task counters. MapRedStats
now has an enum with all of the task counters we want to collect, it is a
subset of the enum in Task$Counter. Task is package private so the enum in it
is unavailable. MapRedStats now contains a map from the enum values to the
values of the counters, if they were set. HadoopJobExecHelper loops over the
enum values and tries to get a value for each counter. As long as the new
getter and setter methods are used the functionality is the same, in particular
for the getter, if a counter was set, it returns the value of the counter,
otherwise it returns -1.

bq. I ran some queries to verify the counters were being populated.

bq. I also ran a few of the unit test queries to verify I hadn't broken
anything.
