* Add check for server_cert falsy and add form validators

* Address comments

* Fix hot reload for charts

* Override tsc options for plugins

Plugins will sometimes have their own `tsconfig.json`, which will
interfere with the dev server config if configured inappropriately.

This change makes sure `tsc` (and `ts-loader`) always compiles to
`esnext` modules, so we don't get "Uncaught ReferenceError: exports
is not defined" error.
