`flightdeck` should consume the SiteSpec Resource Definition and Auto-Generate the Edit-Config page

[ian-flores]

flightdeck shouldn't hard-code the configuration values it showcases in the Edit Config page; it should have a parser that reads the Site Custom Resource Definition and auto-generates the Edit-Config page instead. Initially this parser will read the site.core.posit.team resource and eventually it'll move to reading the site.dedicated.posit.team. We will probably have to use reflections but don't wish to prescribe a solution before tackling the problem.
