Cirrus: Add support for [CI:NEXT]

Rather than supporting a special-mode *just* for netavark/aardvark
testing [in podman CI], support testing with all the latest
`podman-next` COPR packages.

The idea here is very similar to the netavark/aardvark special mode it
replaces.  Most podman-dependencies do not have the level of
comprehensive CI as exist here.  This new CI-mode allows testing
upstream updates to podman-dependencies without needing to roll out
a whole new package/release for them.

Also update documentation for this new mode.
