Dispatcher.connect doesn't include origin field

[dvoytenko]

Bug Description

ConnectOptions interface doesn't include an origin field that's required for the HTTP CONNECT.

Furthermore, it appears that the agent.connect({}) currently fails to execute without the origin field.

Reproducible By

const agent = new Agent();
agent.connect({
  origin: "https://example.com",
  path: "/robots.txt"
 });

This gives a TypeScript error for unknown "origin" field.

Expected Behavior

Origin is accepted.

Environment

Any

@metcoder95 I took a stub at it in #2532. But not sure what to do with backward compat, so I left it an optional field.

Type changes are always considered minor changes, it's fine to make the field required (especially since it doesn't work without it).
