Brian C. Lane b8b5c02d66 composer-cli: Remove all traces of composer-cli
weldr-client has replaced composer-cli so remove all of the code and
tests, adjust various things so they don't expect it to be available,
and rename some things like test/composertest.py to reflect its
exclusive use by lorax.
