Investigate concerns of timeouts for clients with slow internet connections

[brandonsturgeon]

As reported by another developer who implemented a similar system on their server, clients with very slow upload speeds (~1mb/s) could experience timeouts when uploading data to Express.

They suggested that splitting the data into 500kb chunks worked for them. I want to experiment to see if we can find another solution that won't require too much data manipulation.

First, we could try setting the default timeout value on all of our HTTP requests to 2 or 3 minutes (it's 60s by default). We'd have to see what the ramifications of that would be. For example, how many pending HTTP requests can be active at the same time?

Default GMod uses HTTP/1.1, so something fancy like HTTP/2 streaming is out of the question.
