Upgraded to Boot 1.5.6. Updated dependencies of reactive projects to latest versions to make sure the APIs of Boot work with the changes in Spring Data Kay RC1. Upgraded all other dependencies to match and got both the Redis and the Cassandra examples to compile again.
Disabled Cassandra reactive samples for now as they fail at runtime.
Rename the Redis cluster-sentinel project to sentinel and leave a hint in the cluster-sentinel directory that points to the Redis Cluster and Redis Sentinel examples mentioning clarifying the cluster-sentinel naming.
Upgrade to Spring Boot 1.5 snapshots due to minor API changes in Spring Data REST so that recompilation is requited and only 1.5 picks up Ingalls. Upgraded to Querydsl 4.1.4, Spring Framework 5 build profile to 5.0 M3.
Switched to @SpringBootTest in Spring Data Redis samples as the previously deprecated @SpringApplicationConfiguation has been removed in 1.5.
Removed all previous references to snpahosts. Removed explicit version declaration of Lombok as Boot sets that for us in 1.4.
Upgraded Elasticsearch dependency to 2.2 and uncommented the actual sample module as it needs to be updated due to API changes in Elasticsearch and Spring Data Elasticsearch in turn.
Adapt to API changes in entity lookup configuration for Spring Data REST.
Tweaked Neo4j build setup by using the dedicated embedded driver JAR.
Renamed repository folder to repositories. Tweaked package name to reflect module name. Polished formatting in readme. Switched to Spring Boot version property for 1.7 RC1 upgrade.
Original pull request: #162.
Switched to renamed Redis starter POM.
Removed invalid @Transactional annotation from projections example in MongoDB.
Added Mark Paluch as contributor in the root POM.
