CLI help text improvements

[ryanrichholt]

I think there is a lot of room for improvement in the help text for the CLI options.

Ideas, some of these are more than just help text:

• main help subcommand descriptions
• short option exists for -p/--project, but no short option for --pipeline, what about -P, or is this too confusing?
• jetstream project --init? == jetstream init
• jetstream pipeline --init create boiler plate for a new pipeline? or jetstream init --pipeline?
• jetstream project should take a positional argument for project path. Right now it has to be the cwd or passed with --project which is Clunky.
• jetstream project should also show project config data with option to only show info/workflow, etc.
• shorter command alias js? this could be added while leaving the original intact

With my broken hand typing jetstream is a literal pain so an optional short cut is not a bad idea. Would "js" conflict with any linux or python native things?

That's the tricky part, I need something short, but not in conflict with other tools. jetstream would still be the package name (which is already taken on pypi, if we ever wanted to upload there we would need to change) so no issue with python. But, js... is so polluted by javascript names that I worry about conflicts there.
