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

I'd like to update OR downgrade a specific container via http mode.
I'm using localhost:8080/v1/update?images=<image_name> to update my containers via http.
However, in case the new container contain any errors I'd like to downgrade them again to the tag that was used before.

Describe the solution you'd like

Allow to add an image name with a certain tag.
In this way we could define which tag should be used.

Example:
localhost:8080/v1/update?images=<image_name>:<tag>

Describe alternatives you've considered

Another possibility would be an api call "downgrade". The approach, however, would be less flexible as it would only reset the container to the penultimate tag.

Example:
localhost:8080/v1/downgrade?images=<image_name>
