There are times when a request can arrive for a Python function with headers as a list. One of those examples is this header `x-vercel-proxied-for` which apparently is set twice. Example:
`[b'x-vercel-proxied-for', [b'207.81.134.243', b'172.71.147.74']]`
I took a quick scan through the other Python server implementations and I don't think any of them manipulate the value of the HTTP headers, the way the ASGI one does so I think we are good there.
To reproduce:
`curl https://..../ -H "foo: bar" -H "foo: bar"`
Will fail.

This PR update the tests suite to wait for Vercel CLI tarball and then use that tarball to run E2E tests.
This is valuable because it will package all the packages in this monorepo to make the tests follow more closely what will happen in production once merged.
Since the current "Find Changes" step takes about 2 minutes, we run that first (it happens concurrently with the tarball preparation). Then once we complete "Find Changes" we wait for the tarball but it will likely be ready by that point since it also takes about 2 minutes. After both of those steps, the E2E tests continue as usual but with the `VERCEL_CLI_VERSION` set to the tarball.

1. exception from python 3.10:
```
TypeError: As of 3.10, the *loop* parameter was removed from Queue() since it is no longer necessary`
```
Remove the deprecated argument `loop` from `Queue`, which can also be omitted in python version < 3.10
2. exception from Sanic > 21.3:
```
File "C:\Users\Kevin\AppData\Local\Temp\zeit-fun-03f18b2d2c7d7\sanic\signals.py", line 93, in get
group, param_basket = self.find_route(
TypeError: 'NoneType' object is not callable
```
As of Sanic > 21.3, it cannot serve requests immediately after initializing, instead, we need implement the [ASGI lifespan protocol](https://asgi.readthedocs.io/en/latest/specs/lifespan.html) and wait for the startup event completed.
here I complemented the protocol copied from (same source of the previous HTTP procotol): <https://github.com/jordaneremieff/mangum/blob/main/mangum/protocols/lifespan.py>
