feature request: add extra java parameter to fmwcluster

[ltutar]

The following yaml

fmw_cluster_instances:
  'soaCluster':
    domain_name:                     "%{hiera('wls_domain_name')}"
    osb_cluster_name:                "%{hiera('osb_cluster_name')}"
    osb_enabled:                     true
    nodemanager_secure_listener:     true
    log_output:                      *logoutput

connects with t3.

Notice: /Stage[main]/Profiles::Wls::Fmwcluster/Orawls::Utils::Fmwcluster[soaCluster]/Exec[execwlst changeWorkmanagers.py soaCluster]/returns: Connecting to t3://192.168.234.95:7001 with userid weblogic ...

I'll add extra_arguments like copy_domain.
