Create Middleware to extract TeamId and add it to the context

[christianhelp]

We should find all of the places where we can extract a teamId from and if found, we would want to validate that it is not some insanely long value or something weird and then add it to the context. I think some routes would not know their teamId until later on in the logic of the route it self where for those, we would need to set it in the route handler, but we should try to make this as seamless as possible.
