Transmart-Galaxy POC simple analysys implementation

- Introduce AbstractLocalRAnalysisJob class for local R analysis
- Refactor AbstractAnalysisJob class to do not contain r scripts
  specific fields. So it could be superclass for job that runs
  in Galaxy.
- Add simple galaxy job to build histogram. This job creates file
  with 2 columns: patient number and value of selected numeric
  concept, upload it to galaxy, runs galaxy workflow for this file
  and finally downloads workflow output files back to workingDirectory
