This commit converts the bats tests for the plugin cli into the java
packaging test framework. The new tests only use the example plugin to
test the plugin cli. The tests for each individual plugin's contents
after being installed are handled by a new unit test for the plugin
installer added in #58287.
We renamed README.textile to README.asciidoc but a bunch of tests and
the package build itself still pointed at the old name. This switches
them the new name.
This is in preparation to move to nested virtualization which is much slower
than the bare metal setup we use right now, but parallelizes better
resulting in a net win.t
The system level tests for our distributions have historically be run in
vagrant, and thus the name of the gradle project has been "vagrant".
However, as we move to running these tests in other environments (eg
GCP) the name vagrant no longer makes sense. This commit renames the
project to "os" (short for operating system), since these tests ensure
all of our distributions run correctly on our supported operating
systems.
