blueprints/changes is different, each blueprint has it's own total,
limited by the call's limit. So it needs to find the max total of all
the requested blueprints.
Add a limit argument to all potentially paginated results, equal to
whatever the composer backend is the total number of results. This still
has the potential to provide truncated data if the number of results
increases between the two HTTP requests.
Resolves: #404
This patch does two things:
1) Add "compose list", which lists compose UUIDs and other basic info,
2) Fix up "blueprints list", "modules list", "sources list", and
"compose types" so their output is just a plain list of identifiers
This is the same as the output at the top level, just trimmed down to
only the options for a single subcommand. It's trigged by providing
"help" or "--help" as a subcommand option.
