System tests are used for testing the *podman* CLI in the context of a complete system. It
requires that *podman*, all dependencies, and configurations are in place. The intention of
system testing is to match as closely as possible with real-world user/developer use-cases
and environments. The orchestration of the environments and tests is left to external
tooling.

-options to the command by default. When you run system test, you can set GLOBALOPTIONS,
-PODMAN_SUBCMD_OPTIONS or PODMAN_BINARY in ENV to run the test suite for different test matrices.
