Remove old school TOCI files

Removes a bunch of the now deprecated toci_* files which now
exists in a different form under tripleo-incubator/scripts/devtest_*.

These scripts served us well over the past few months but the
time has come to focus this project solely on CI.

Well done old toci_*. Thanks for helping us raise the bar.
