Add @posthog/plugin-globals (0.0.1)

[mariusandra]

Changes

• Trying out the @posthog/plugin-globals package. No matter what we'll do with meta, we still have globals and will probably want some things to remain globals. This adds support for them.
  

• The plugin-globals project needs to be extended with other globals. Currently only posthog is there.

Checklist

• Tests for new code

Thanks for the contribution!
I personally am okay with writing things like that. I am concerned however that anyone who does not work at PostHog may find the increased cognitive load of additional tsconfig and one more package discouraging from writing plugins with TypeScript or in general. It's also more thing to maintain for us. That's why I'd really really like all te definitions to be in the single plugin-scaffold package.

Fair enough re: keeping things simpler. It's possible to do the same thing with the @posthog/plugin-scaffold package: PostHog/plugin-server#274 (comment) -- we'll just have to import it from a different source in posthog & plugin-server to not get the globals, but that shouldn't be too much work, considering it's a mostly one-off affair (a few times).
