Update support documentation for modern times master
Summary: Basically similar to D13941 but a little more extreme: - Really strongly emphasize reproducibility for bug reports, and set users up for rejection if they don't satisfy this. - Really strongly emphasize problem descriptions for feature requests, and set users up for rejection. - Get rid of various "please give us feedback"; we get plenty of feedback these days. - Some modernization tweaks. - Split the support document into: - Stuff we actually support for free (security / good bug reports / feature requests). - Stuff you can pay us for (hosting / consulting / prioritization). - A nebulous "community" section, with appropriate (low) expectations that better reflects reality. My overall goals here are: - Set expectations better, so users don't show up in IRC expecting it to be a "great place to get amazing support" or whatever the docs said in 2011. - Possibly move the needle slightly on bug reports / feature request quality, maybe. Test Plan: Read changes carefully. Reviewers: chad Reviewed By: chad Differential Revision: https://secure.phabricator.com/D14305
