Revert "Disable WebSocket connection throttling in the network service" 

This reverts commit 3bce0223.

Reason for revert: This is no longer needed in ToT because it has already been merged and released for M77.

Original change's description:
> Disable WebSocket connection throttling in the network service
> 
> Permit any number of connect requests to be pending in the network
> service.
> 
> Note that per-server WebSocket connection serialisation is still
> applied, so this doesn't permit denial-of-service attacks against
> servers.
>

Test that WebSocket connections are throttled.
On success, you will see a series of "PASS" messages, followed by "TEST COMPLETE".
FAIL openedCount should be 255. Was 300.
PASS openedCount is 255
PASS successfullyParsed is true
TEST COMPLETE
