Support multiple review resources in Airlock Review VM UI

[jjgriff93]

As a follow on from #2738 we should support multiple review user resources in the UI to create a screen like this: https://www.figma.com/file/Ncl8TJsFf2WKf3frrqTbtq/AzureTRE-OSS-UI?node-id=1293%3A27999

This will involve modifying the reviewUserResources property of the airlock request to include the reviewerId in the form of a dictionary:

"reviewUserResources": {
    "<user_object_id>": {
        "workspaceId": "XXX",
        "workspaceServiceId": "XXX",
        "userResourceId": "XXX"
    }
}

This will allow the UI to then filter for the signed-in user id and also list the other ids to show who else is reviewing.

The API will also need to be modified to only allow one review VM per user. On /Create-review-resource, the API should:

• Check if the current signed in user has a resource already in the reviewUserResources dict
• If so, do a call to get the status of the resource. If it is running and healthy, return 409 Conflict
• If not, delete it and create a new one, then replace the userResource details in the request
• Update UI

• Could improve migration by doing a look up of the resource and assigning the correct user to it
