Force refresh server assessment (meta)data

Hi joetahsin ,

The same article says: "Scanning begins automatically as soon as the extension is successfully deployed. Scans will then run at four-hour intervals. This interval isn't configurable.". 

Also, you can trigger an on-demand scan to expedite the process: https://docs.microsoft.com/en-us/azure/security-center/deploy-vulnerability-assessment-vm#trigger-an-on-demand-scan
