Listen to the new project changed event from the VM and keep track of the state in Redux.  Update it as appropriate.

Known issue is that the project is marked as "changed" immediately after it's loaded. This is due to asynchronous event emitting while the project data is loaded, and needs an update to the VM to fix.

Move cloud connection logic into its own HOC and add canUseCloud flag to control whether to show the new cloud variable options in the variable modal.

Set up cloud provider and attach it to the VM. Obtain information about cloud host and username from props.
