Reduce number of internal Cypress network requests

[brian-mann]

Current

Currently Cypress sends up to 18 network requests for internal traffic. This is obtrusive to users, mixes with their own traffic, and reduces performance.

All of these requests come from Cypress itself.

Proposal

• Consolidate as many requests as possible
• Namespace these so they are more clearly identified as internal cypress network requests.

[brian-mann]

We were able to reduce the network requests by 50% from 18 to 9.

We consolidated a bunch of JS, CSS, icons, and set socket.io to websocket traffic only so it does less thrashing about.

It's probably possible to golf this down a bit by consolidating the fonts.

The code for this is done, but this has yet to be released. We'll update the issue and reference the changelog when it's released.
