Cirrus: Add dedicated rootless mode testing
Certain integration tests require execution as a regular user. This is acomplished by `PodmanTest.PodmanAsUserBase()` wrapping a specialized execution environment, in `test/utils/utils.go`. However, doing this requires passing through python, which vastly increases the complexity of debugging low-level problems. This commit introduces a new parallel task, run as a regular user on the VM as set by three environment variables. All commands executed in the ``rootless_test.sh`` script, will occur as a real user with a name and home directory, just as `$DIETY` intended. All env. vars established during `environment_setup.sh` (for root) are available. The PR source in `$GOSRC` and `$GOPATH` are owned by this user, and ready for use.

+### ``rootless_testing`` Task
+
+***N/B: Steps below are performed by automation***
+
+1. After `gating` passes, spin up one VM per
+ `matrix: image_name` item. Once accessible, ``ssh``
+ into each VM as the `root` user.
+
+2. ``setup_environment.sh``: Configure root's `.bash_profile`
+ the same as for other tasks. However, also add a regular
+ user account, chown all the source code to them. Set up
+ fresh ssh pub/priv. keys for the root user, adding the
+ public part to the user's `authorized_keys` file.
+
+3. As root, call ssh to connect to localhost as the user,
+ and run the ``rootless_test.sh`` script from the source
+ tree. This is needed so the user has a clean process tree
+ and environment - i.e. without `sudo`, `su`, `runuser`,
+ etc. in the mix. From here, all testing as the user may
+ be performed.
