Old version of commons-logging drags old version of servlet-api through infinispan-spring

infinispan-spring 8.1.1. has a dependency on an old version of commons-logging (1.1) which in turn has a "compile" dependency on servlet-api 2.3, so in maven the old servlet api is dragged into the build and then conflicts arise when deployed on a servlet container.

The dependency on commons-logging should be updated (1.2 has a "provided" dependency on the servlet-api)
