[WIP] Refactor ManageIQ setup

[Fryguy]

This commit refactors the ManageIQ core and plugin setup and update to

• DRY up duplication
• Use consistent ENV vars for skipping parts
• Log nicer locally and on CI
• Prevent duplicate bundle update on CI

WIP, because I might want to refactor some of the before_install scripts from the plugins as well, similar to ManageIQ/manageiq-providers-amazon#744

nice changes

You know, I often want to call ./bin/update --no-automate --no-bundle
It would be easy for me to add tab _complete().
I keep telling myself that env vars are just the same thing but for me it just isn't.

This resonating with you at all?
