Moved HBase and HoyaAM setup to config.xml driven; accumulo in progress.
At this point everything compiles and the HBase tests pass
TestAccM1T1GC1Mon1 passing; all roles other than tablet/master are assigned to "other"
Accumulo tests working with xml template driven configs; pulling back on memory requirements for mini yarn cluster instances critical
fix YARN  memory requirements for HBase instances in the test base -so doesn’t break if an option such as "max" is chosen in the production templates
reformat LoadGenProvider prior  to rework
all providers except the HoyaAmClientProvder no longer do anything in prepareAMResourceRequirements
fix a comment indentation in YarnMiniClusterTestBase
Loadgen code updated to template model, even though it isn’t implemented service-side
move declared minicluster RAM requirements to a constant and adopt everywhere
