Cleanup existing Files App UMA Metrics.

1/ Fix up the FileManagerRootType enums to reflexct the values sent.
2/ Add back the deprecated "ADD_NEW_SERVICES_MENU" so that the enums
   have a consistent value. Note that there will be a time period where
   the accounting is incorrect for roots > 15.
3/ Add expiry to all FileBrowser metrics, M79 which is the last release
   of 2019.
4/ Mark as obsolete FileBrowser.CloudImport.UserAction which does not
   appear to exist anymore.
