Run actions before server starts

[ezeheinke]

Hi! I am trying to find a way to run some actions before our app starts. For context, we have a blitzjs app that has the standard blitz-client.ts blitz-server.ts files.
And we run it with blitz start blitz dev. So far, like in the tutorial and docs.

But, we have the need now of running some initialisations when the server starts, what is the best way to achieve this? Custom server? Would I miss the plugins functionality that setupBlitzServer gives if I go down this route?
