Add proposal for secret and configmap files mode bits

This is a proposal to address https://github.com/kubernetes/kubernetes/issues/28317.

@thockin: Sorry if you preferred not to be CCed, I thougth you'd be interested :-)

I think this is always the case, but let me say it one more time just in case: as this is a PR, ALL the feedback is more than welcome!

It's my first time in kubernetes, so sorry in advance if this is obviously wrong. What I realize now is that I forgot to add the headers to the proposal. Is there some script to add them? Or should I just c&p from some other proposal?


Thanks a lot,
Rodrigo
