Subject: Speed up copying OpenShift examples
* The `copy` module does not scale to hundreds of files
* Replace `copy` with `unarchive`
Create a temp dir locally to tar all the OpenShift examples into. Make
the dest dir on the remote side, drop examples in place with the
`unarchive` module.

+# Copying Examples
+#
+# We used to use the copy module to transfer the openshift examples to
+# the remote. Then it started taking more than a minute to transfer
+# the files. As noted in the module:
+#
+# "The 'copy' module recursively copy facility does not scale to
+# lots (>hundreds) of files."
+#
+# The `synchronize` module is suggested as an alternative, we can't
+# use it either due to changes introduced in Ansible 2.x.
