title: Spring Cloud Config Client re-loading config every 30 seconds
body: <p>I'm working to enable the use of Spring Cloud Config and have everything working. However, I'm seeing INFO messages in my service app logs that shows that the Cloud Config Client is looking to re-load the configuration from the server about every 30 seconds. I cannot find anything in the docs or even in the code to suggest why this is happening. I really don't want my services polling the config server nearly that often, and ideally I'd like to turn it off, so I have some more control over when a config refresh happens.</p>
  
  <p>Anyone have any ideas?</p>
