Overall "Grove in Production" documentation

[patrickmcelwee]

We should have an overview on running in production, which will link to things like:

1. building the UI into static files;
2. serving those with the middle-tier, or a reverse proxy,
3. HTTPS;
4. pm2

Here are some bits and pieces:

this README has "Run your project in production": https://project.marklogic.com/repo/projects/NACW/repos/grove-react-template/browse

this one has some about https: https://project.marklogic.com/repo/users/pmcelwee/repos/grove-react-ui/browse

grove node has https doc: https://project.marklogic.com/repo/projects/NACW/repos/grove-node/browse/HTTPS.markdown
