make the bootstrap process more transparent, resilient about wasabi

A branch for this can be found here: feature/unbootstrap

@AndreaSuckro thoughts about a --dry-run option that is false by default yet when set (eg ./bin/wasabi.sh --dry-run bootstrap) it sets a global (eg dry_run=true) that is supported by every command? and each could could have an associated here-document that it echos out and returns with exit status 0 at the end of the call chain? something like, pseudo-code:

[ $dry_run ] && foo_doc; exit 0

After taking a look at everything we install, I am not so sure anymore whether the uninstall command is a good thing (e.g. bash, git, maven ...). Some dependencies are pretty fundamental and a command like this would seriously screw up the system of the user when used without caution. I now added a super simple list-dependencies command, I think that is a first step - your suggestion sounds even better - I am just not sure how we would dynamically generate the here-documents so that they dynamically list all the dependencies for example.

i concur

i will see what i can do to spike in one example of a --dry-run here-doc as an example

Maybe this will help homebrew-bundle?

I know this is super old, but coming to this as a new wasabi user the bootstrap opaque and fragile. For example, if you run this today on a mac you'll install node ver 9.X and then many of the node modules will fail, things won't compile, etc.
Using something like nvm is ignored also, because the check for node is based on brew list node instead of actually just checking the node version on the command line.
Also, docker from cask is way behind docker's current recommended install on a mac. It would be nice just to say:
"You need these packages to compile: [foo:6, bar:1, baz:2.3], this to run: [foo:6, bar:1], and this to develop: [foo, bar, baz, blah, etc]"
and then offer to install them with the bootstrap with a listing of what it will do. There are some force commands in there that kind of jacked my system up and took me a while to re-set it up.
