Added options to set wls_settings by extra resource

Edwin,

No you can set the defaults for wls connection in your manifest. Use the following code to set the defaults.  

```puppet
wls_setting { 'default':
  admin_server => 'localhost',
  connect_url  => 'http://localhost:7001',
  user         => 'wls',
}
````
You can name it what you like. It only remembers the last setting though. 

 You can set next defaults:

- user
 -domain
- domains_path
- connect_url
- admin_server

If you need more, checkout `wls_setting.rb`
