[OE-core] Removing netbase from an image

[Jack Mitchell]

I am attempting to remove netbase from a custom image. I would like to 
replace it with connman. I have added connman through 
EXTRA_IMAGE_INSTALL, however netbase is brought in via 
packagegroup-core-boot.bb which funnily enough has some very important 
features and I would like to keep.

What would be the best way to make this replacement. Should I copy 
packagegroup-core-boot.bb and keep a local copy, while keeping it in 
sync manually? Alternatively, I notice quite a few packages in 
packagegroup-core-boot have a VIRTUAL-RUNTIME_* define. Would it be 
worth having a VIRTUAL-RUNTIME_network ?= "netbase" which could be 
overridden?

Thoughts?
