Switch to default_deploy_interface = autodetect

This changes the default deploy interface from direct to autodetect[1]. For
all existing supported scenarios this will result in the direct
interface being used during deployment, but this will also enable bootc
container images to be used for deployment.

The check for bootc only occurs when the image source uses an oci:// URL
protocol.
