test/system: Make tests non-destructive
This allows to run the test suite without having to worry about blasting the whole local state of Podman. This is done by creating a configuration file with a custom path for the storage of Podman and specifying the config file using an env var. The used location for the temporary storage is located either under XDG_CACHE_HOME and if the one is not defined, $HOME/.cache is used instead. The data are namespaced. This follows the XDG Base Directory Specification[0]. Other locations could be /tmp or /run but those locations usually use tmpfs and that filesystem can not be used by Podman[1] due to missing features in tmpfs. https://github.com/containers/toolbox/pull/818 [0] https://specifications.freedesktop.org/basedir-spec/latest/index.html [1] https://github.com/containers/podman/issues/10693#issuecomment-863007516

The tests are meant to ensure that Toolbox's functionality remains stable
|

throughout updates of both Toolbox and Podman/libpod.
|
||||
|
||||
**Warning**: The tests are not executed in an isolated environment. Running the
|
||||
tests will clear all podman state (delete all containers, images, etc).
|
||||
The tests are set up in a way that does not affect the host environment.
|

Running them won't remove any existing containers or images.
