The java based distribution tests currently have a single Tests class
which encapsulates all of the tests for a particular distribution. The
test task in gradle then depends on all distributions being built, and
each individual tests class looks for the particular distribution it is
trying to test. This means that reproducing a single test failure
triggers all the distributions to be built, even though only one is
needed for the test.
This commit reworks the java distribution tests to pass in a particular
distribution to be tested, and changes the base test classes to be
actual test classes which have assumptions around which distributions
they operate on. For example, the archives tests will be skipped when
run with an rpm distribution, and vice versa for the package tests. This
makes reproduction much more granular. It also also better splitting up
tests around a particular use case. For example, all tests for systemd
behavior can be in one test class, and run independently of all tests
against rpm/deb distributions.
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.
