Make more use of Make throughout the bootstrap instructions

[jamezpolley]

I feel like this simplifies the initial bootstrap a bit - it lets me get up and running quickly without too much copy/paste or fiddling, but the exact commands are still easy to read in the Makefile.

@mlandauer Do you want me to split this into two changes - one that's just the Make changes and one for the rest of the formatting?

Yes please. Rule of thumb is each commit should be an atomic change that fits together. I'm happy with these changes being bundled into the same PR but they definitely shouldn't be in a single commit. There's at least separate commits for:

• Adding new makefile targets and converting over README instructions to use them
• Adding a TOC to the README
• Change instructions on how to check that minio is ready

But before you put effort into doing that let me add some comments to your existing commit

@mlandauer I think this is ready to go

Thanks @jamezpolley!
