lei config --edit: use controlling terminal

As with "lei edit-search", "lei config --edit" may
spawn an interactive editor which works best from
the terminal running script/lei.

So implement LeiConfig as a superclass of LeiEditSearch
so the two commands can share the same verification
hooks and retry logic.
