This PR updates the reports sent to include a more detailed OS version string, similar to what is used by the usagereporter and systeminfo call.
It also reports parts of the destination hostname, if using S3 and the host is a known public cloud. This is done to avoid leaking internal hostnames or actual bucket names, but still provide some way to identify what storage service is used.
Added support for `--portable-mode` and `--server-datafolder` for the CLI, ServerUtil, and Agent.
Fixed a few places where file reads were not cached properly.
Moved some responsibilities of UpdaterManager into DataFolderManager.
This now supports storing `machineid.txt` and `installation.txt` inside the path pointed to by `--server-datafolder` or alternatively with `--portable-mode`.
It is possible that some fringe backwards compatibility is lost with this update.
Fixed an issue with AutoUpdater crashing on check/download.
This fixes#5902
