Commit seed code for validation-scripts

This imports the initial seed code for validation scripts.

These files were imported from a tarball with the SHA1SUM
ce2ae49c82546b987c8ad2f68ac43d94b4934818.

From the contents of the tarball, some errant .pyc files were removed,
and a .gitignore file was added. The result matches exactly the contents
of the origin private repository at hash 88c656e.
