Support disabling global context and page

[nickgarlis]

🚀 Feature Proposal

Apologies if there is already a way to do this. It looks like this preset spawns a new context and page for each test. Is there a way to disable this behavior ?

Motivation

There are some cases when I am testing with an unknown number of contexts and pages. This is when I have to manage their creation on my own.

Example

Maybe by setting something like that into the config file ?

module.exports = {
  page: 'none',
  browserContext: 'none'
}

Pitch

I think it would be useful for those who only need a global browser instance across tests. I'd like to hear your thoughts. I'd be happy to help by opening a PR for it.

A PR would be helpful.
