This PR adds the option to limit the available modules to just the set of specified choices.
If no option is set, all modules are available (default).
If the option is set, only those in the list are available (whitelisting).
The options are:
- `--allowed-backend-modules`
- `--allowed-encryption-modules`
- `--allowed-compression-modules`
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
