Adds a class that allows tests to export a local directory to an exporter via sshfs. In order to prevent the exporter from being able to access any file that the user has permission for on the file system (which would allow it to read SSH keys for example), the SFTP server is run in an isolated container by default using podman, although this can be overridden to use docker or directly execute the SFTP server if the exporters are trusted.

It seems that the podman in Ubuntu 22.04 tries to build the other targets as well, so this should be a different Dockerfile.

Hmm, how do we want to tell the user that we expect this image to exist locally? Do we want to have a runtime check for the image or is documentation enough?

We might want to connect to an exporter for a specific resource (similar to ManagedFile) or to the target as well. So I'd prefer to pass host/port instead of a resource. That would mean passing a config separately as well.
@JoshuaWatt Do you see a downside?
