Business Edition - Add ability to see if an update available

[Barrow1990]

Is your feature request related to a problem? Please describe.

If utilising Portainer - Business Edition then add an attribute under each container if the container is upto date

Describe the solution you'd like

Another attribute stating - Up To Date: True / False
Can retrieve the status of the container via the api endpoint: /docker/{environmentId}/containers/{containerId}/image_status

This returns for an outdated container:

{
  "Status": "outdated",
  "Message": ""
}

and for a indate container:

{
  "Status": "updated",
  "Message": ""
}

Describe alternatives you've considered
