Re-add deprecated scripts, drop shebang from cli modules (#187)

This is a follow-up change to re-add deprecated scripts so we don't
break any existing use of those scripts while folks migrate to better
ways to invoke them.

Additionally, we can drop the shebangs and executable permissions from
the CLI modules that were renamed in the previous commit.
