This test is the same as Multi Site Basic test, but all the site-specific settings have been moved out of the server.json INCLUDING the web root of each site. The site-specific settings have been placed in site1.json, site2.json, etc files in a folder above the web roots. Note it was neccessary to edit the relative virtual directory path to be relative to the folder each .site.json file lives in. The sites block in the main server.json uses the siteConfigFile key to point to the file for each site. All the same tests for Multi Site Basic should work here with the same results.
