WIP Add support for passing a charm/bundle id as a deploy-target query parameter

You can now add a query parameter `deploy-target` with the value a charm or bundle id to the url when loading the GUI to automatically deploy the charm or bundle to the environment.
After looking into this, using immediate: true will help deploy the charm faster but we will still need to create a machine and place the unit on it so overall it won't gain us anything. Going to leave it as-is
