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.
