can we update this to something like https://github.com/aws/aws-lambda-dotnet/pull/1955/files#diff-16dac3e7db3ba4a144e7ac3063ba31b74a53037cb85cc1a5e35410efb0d6393dR311? the reason being is depending on the developers machine/codebuild machine, the above ports may not actually be free. I think we should use TcpListener for the OS to give us free ports

The point of the change I'm making is so we can atomically check what the next port is that other tests are not using. I believe the TcpListener is a bit overkill as these port ranges are always free in the CI. Even on our machines, these ports are usually not used.

The int.MaxValue is used to workaround a microsoft bug. We don't actually intend to wait that long. We use it in other repos. Sometimes the process hangs, and when we pass int.MaxValue the process stops hanging.
