This is required by https://issues.jboss.org/browse/ENTESB-7959 . See also the discussion on WildFly Dev mailing list: http://lists.jboss.org/pipermail/wildfly-dev/2018-May/006494.html

Short version: To expose Camel CXF endpoints, we need to clone the DeploymentInfo of the main deployment and customize some of its aspects. Currently, the collection fields of DeploymentInfo are not adjustable in any way: their getters return unmodifialble wrappers while clear and per-item remove methods are missing. Clear methods would be enough for what we need.

A PR follows.
