Remove Spring warning about spring-jcl and commons-logging

[npepinpe]

Description

Spring displays a warning at startup if both spring-jcl and commons-logging are found in the same class path:

Standard Commons Logging discovery in action with spring-jcl: please remove commons-logging.jar from classpath in order to avoid potential conflicts

As per their own Spring Data project (which also uses the Elasticsearch client), it seems fine to simply exclude commons-logging.
