Allow plugins to depend on other plugins

Is there any way to specify that one plugin requires another to be loaded? For example, if I’ve written a plugin that processes messages from gpsi in order to do something special, I’d like to ideally ensure that gpsi gets loaded without having to tell a user to make sure they’ve set --plugins.load gpsi my-plugin.

Barring that, it would at least be nice to have a final list of loaded plugins so I could throw an error or log a message noting that gpsi (or whatever other plugin I depend on) isn’t loaded.

Similarly, it would be helpful to be able to supply additional options to the plugin I depend on. For example, I am working on a plugin that requires a special post-script be used for Browsertime. It would be nice to somehow explicitly declare that I depend on Browsertime and provide the path to the post-script to load from my plugin instead of telling users to make sure they set that Browsertime option appropriately on the CLI.

Lets create an issue the coming days then the coming days to open the Browsertime from sitespeed.io to async a JavaScript, it’s a nice feature but no one has focused on opening it up from the outside.
