assisted-installer-controller logs should be included in must-gather data

The agent-based installer and assisted-installer create a Deployment named assisted-installer-controller in the assisted-installer namespace. This deployment is responsible for running the assisted-installer-controller to finalise the installation, mainly by updating the status of the Nodes in the assisted-service API. It's also required to be able to install platform:vsphere without credentials in 4.13 and above.

We want the logs for this pod to be included in the must-gather file, so that we can easily debug any installation issues caused by this process. Currently it is not.
