telemetry: add request_id field for code block actions

From @chenkc805

For a "chatID", I'd like to be able to link specific chain of events together:
chat/command executed --> chat/command response --> code copied --> code pasted

This PR adds request_id to each Interaction so that when we display the code block in the UI, we will be able to refer back to the request when the code was generated:

• add requestID parameter to copy and insert callback functions

Test plan

Ask Cody a question that generates a code block, and then copy the code. they should have the same request id as the request that generated the code

Preventive approval with a couple of inline comments.
It would be great to add/update a couple of unit tests to test this change in a follow-up PR.

[valerybugakov]

Would it be possible to use camel-case everywhere in the PR?

Suggested change

	request_id?: string
	requestID?: string

[valerybugakov]

Why date instead of uuid.v4() that we used in other similar places? By clicking twice on the new chat button, I can create two sessions with the same ID.
