tests: add CLI dummy command-exec tool

This adds some common CLI testtool code as well as a tool that has a
bunch of commands to be poked for their correct processing.

The tool doesn't work correctly from a script at stdin at this point
because the vty code will throw away all buffered when it sees EOF, so
the tail end of the input file is lost.
