Design Issues: The process to resolve lower level architectural and design conundrums

See https://github.com/OpenLiberty/open-liberty/projects/3

The scope of the design issue resolution process is not investment choices, not usually high customer impact choices(handled by UFOs or voted on by the POC) but more getting an architectural opinion.

How the process works:

1. Create an issue
2. Tag it with design issue
3. Get it on to the correct column of https://github.com/OpenLiberty/open-liberty/projects/3
