Introduce CSV exporter

In order to add the new implementet CsvExporter, I resructured the analysis:

• Now the analysis is carried out by the AnalysisExecutor.
• The AnalysisExecutor fetches the data from prometheus, export it to csv and afterwards send to to further analysis to the external slope checker.
• Additional analysis can easily be added

Only a couple of comments. Please rebase after fixing them.
