Add operator survey to repo

[jberkus]

This adds the operator survey summary, in MD format, to this repo. It also creates a WG subdirectory, which seems like a useful place to stash files related to WG activities.

Probably better to put the survey under the existing directory docs (create a subdirectory survey under docs)?

Nit: etcd is always lowercase. There are several places in the doc to update this.

Suggested change

	# Etcd Operator Survey Results
	# etcd Operator Survey Results

Isn't the Docs folder going to eventually hold the docs for the actual operator? In which case we don't want survey results there.

I would make a case for user facing operator docs to go on the etcd website for the most part.

The goal is to organize all documents under one directory. It's similar to etcd documents, in which there are different kinds of docs.
