Description of problem:
mod_cluster metric properties are parsed for but are never applied
Version-Release number of selected component (if applicable):
Whole 6.x tree
Steps to Reproduce:
1. setup a custom load metric with properties
2. start EAP
props are not applied
props are applied
Verified with 6.3.0.Alpha1 (DR0).
Documentation: this is a bugfix, we should document this. People might not have been aware that these were never applied. It might break their existing custom load metrics in case they did not have correct configuration in previous versions.
