Cleaning up the design-proposals directory #651
Description
The go proposals repo is super clean and all kind of have the same format, see https://github.com/golang/proposal/tree/master/design.
Things we might consider:
-(dash) vs_(underscore): Throughout this repo there is a mixture of-vs_in filenames (example https://github.com/kubernetes/community/tree/master/contributors/design-proposals) and it is kind of driving my OCD insane... what if we picked one :)... really not trying to start a bike shed could care less which one, as long it is consistent. It does seem like-is more common though...- ensure all have same format: seems wrong to change the old but maybe each should at least have a table of contents and add a template.md for the future...
