Add run list command

[adamconnelly]

Added a new command to list the runs for a stack.

I've tried to keep the amount of data in the table output minimal while still being useful, but we'll probably need to tweak it in future. The JSON output only contains fields that are relevant for a tracked run.

Here's what the table output looks like:

Here's a sample of the JSON output:

[

    "branch": "pr-promotion-branch",

      {

        "createdAt": 1661356291,
        "username": "adamconnelly"
      }
    ],
    "commit": {
