Cleanup Transactions and extra files

[zloster]

Review again the rules about the transactions and the update test: https://github.com/zloster/FrameworkBenchmarks/blob/dw8-jdbi/frameworks/Java/dropwizard/src/main/java/com/example/helloworld/db/jdbi/WorldRepository.java#L46-L61 - I think this is forbidden by the rules - to have one big transaction around the reading and updating the values.

After this cleanup: https://github.com/zloster/FrameworkBenchmarks/blob/dw8-jdbi/frameworks/Java/dropwizard/src/main/java/com/example/helloworld/db/jdbi/WorldJDBIImpl.java

The rules for the updates:
http://frameworkbenchmarks.readthedocs.io/en/latest/Project-Information/Framework-Tests/#database-updates
Number 10
So the transaction have to be inside the for loop.

[zloster]

Some cleaning later a new branch is ready. Currently local testing.

[zloster]

The new branch is jdbi. There were issues and clean merge with the current master was not possible.
Local testing OK.

There are some possibilities for clean up and so on but they will wait for better times.

[zloster]

There were some problems with the manual diff and the transition to new branch. And I haven't checked the results. So reopening. The local tests are currently running

[zloster]

The custom results viewer is here:
https://www.techempower.com/benchmarks/#section=test

Paste the results.json and adjust the duration or use EtherCalc online spreadsheet.

The results show significant problem with the update test which currently is using transactions.
