Event Hub

[MichalCz]

What?

This introduces an event bus that allows instances to send events to each other within a single hub. It also exposes a hub level API.

Why?

This adds a communication layer between instances that works fairly quickly and allows sequence implementors to broadcast messages between
running instances.

Usage:

In a sequence you can use:

• Seq1/index.js: this.emit("myEvent", "my string of event data")
• Seq2/index.js: this.on("myEvent", () => doSomething())

Clickup Task:

How it works:

• CSI controller has a tiny change to expose events to host
• Host handles most of the forwarding
• The BDD tests are a good starting point

Review checks:

These aspects need to be checked by the reviewer:

• Verify and confirm operation (please post a screenshot)
• All STH tests pass
• All Scramjet Cloud Platform tests pass
• Documentation is updated or no changes
