Description
While testing #32981, I found that --ipam-driver does not appear to get set in the --config-only network, and thus the IPAM driver is not used in global scope. I also have noted this finding in #32981
Steps to reproduce the issue:
- when no --config-only flag is specified, --ipam-driver is used properly and I get a subnet and gateway from the IPAM driver
- when setting --config-only, the IPAM.Driver appears to not be set even though it is specified in my example with --ipam-driver
Describe the results you received:

^^^ 👍 Driver is correctly set to ishant8/sdip:latest, and Subnet and Gateway are obtained from the IPAM plugin

^^^ 👎 Driver is not set in config-only network, nor in global-scoped from config-only, and IPAM driver does not return Subnet nor Gateway
Describe the results you expected:
- I expected the IPAM Driver to be set in the config-only network, and available to the global-scoped network which references it
