Add etc/bash_completion.d/composer-cli

Here's a bash_completion file for composer-cli! It completes known
commands, subcommands, and flags, plus arguments to flags that take
arguments, and if you've got write access to the socket it'll also
autocomplete:

* source names for commands that need source names
* blueprint names for commands that take blueprint names
* compose uuids for commands that take compose uuids
  * intelligently only suggests appropriate uuids - e.g. only
    suggests uuids of running composes for "compose cancel"

NOTE: bash completion scripts are horrible and this is no exception.
Please forgive me.
