SO WorkflowAction refactor

- extract traverseUserParamsService() method from WorkflowAction class to UserParamsServiceTraversal class
- move methods used only in traverseUserParamsService() method to UserParamsServiceTraversal class
- change method signature from traverseUserParamsService to getResourceListFromUserParams()
- create WorkFlowActionCommon for duplicated code
