feat: groups pattern full match support

[AndersDJohnson]

Config groups for recording should support full match objects to specify which requests are recorded. This would give full parity with the API for mocks. We would support a limited subset with at least matches in static JSON config (the same subset supported in #414 - and maybe regex too if we solve #276 or with { path: { "$regex": "a.*b" } }), full features with programmatic use, and maybe also some limited support with CLI args for dynamic groups (#274).

So we could write the following:

{
  groups: {
    users: {
      match: {
        path: "/some/service"
        query: {
          someParam: /someValue.*/,
          otherParam: value => ['a', 'b', 'c'].includes(value)
        }
      }
    }
  }
}
