Server group targeting fails (add used on list instead of append)

[Omar007]

Targeting to dynamic clusters seems to still be WIP but even if you currently try to do so, it bails out early and crashes on a call to add() in wlsdeploy/tool/util/target_helper.py.
It seems the target is supposed to be added to 'cluster_members' on line 360

weblogic-deploy-tooling/core/src/main/python/wlsdeploy/tool/util/target_helper.py

Line 360 in 3058d27

cluster_members.add(target_name)

but a call to 'add' is used instead of 'append', resulting in an AttributeError.
