remove kic overlay network for docker-runtime

[medyagh]

After the refactor that we fixed the control-endpoint in the config, we no longer need to use kic overlay network.

After this PR:

• save 3 seconds by not waiting for applying kic overlay network on the default runtime (docker)
• save disk space by not storing kindnet image
• make preload images 78mb smaller for docker ( for the next version of preload images)

does this PR affect multi node ?

no.

the mutli node start works fine as is now

other operations of multi node is broken even before this PR see #7423
I belive to make this service work in multi node we currently need flannel (which means we do not use kic overlay network anyways_

FUTURE PRs:

this PR does not remove kic overaly for containerd and crio as they are still needed till we address #7428

LGTM -- could you please bump up the preload version here? Then this should be good to merge

good idea, I will do that in a separate PR so we can have the images generted first for the tests
