Remove openshift inventory plugin (#252)

* Remove openshift inventory plugin

This removes the openshift inventory plugin which has been deprecated
since version 3.0.0. The tests have been updated to retain coverage of
the connection plugin, which is still supported.

* Update version in Makefile

* CI fixes

* Update version info in build scripts

* Set ansible remote directory

The security policy on the pod is preventing ansible from writing to /.
Set it to /tmp which should be writable.
