Upgraded APIs: Flink (0.8) and HBase (0.98.x) + profiles

I had to create an hadoop.core.version variable to manage the fact that cloudera has different versions for hadoop-core and hadoop-common..
Why did you go for an empty ``configure()`` method? 
Creating a table and a scanner does probably include communication with the HBase master, which does not come for free. Depending on how expensive these operations are, it might make sense to only do this once.
