#297 - Upgraded to Boot 2.0 and Spring Data Kay.

Bumped version number to 2.0. Upgraded to Spring Boot 2.0.

Stuff disabled in the meantime:

- Cassandra: needs API adaptions in configuration
- JPA > Security: test fails with weird Hibernate error
- Redis > Reactive: API updates needed
- Solr: configration updates necessary

adjust versions

Updated elastic search to the new version.

Fixed the reactor version to Bismuth-BUILD-SNAPSHOT. This probably should be undone when boot references the proper bom.
