Remove Init function from the parallels driver definition

[legal90]

Fixes #9493

That's needed for minikube to stop treating parallels as a built-in driver and use RPC calls for calling its functionality.

Hi @legal90. Thanks for your PR.

I'm waiting for a kubernetes member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.

Can one of the admins verify this patch?

This patch is based on the following logic:

minikube/pkg/minikube/machine/client.go

Lines 92 to 94 in 97d96bf

	if def.Init == nil {
	return api.legacyClient.NewHost(drvName, rawDriver)
	}

But I'm a bit confused by the name legacyClient there. So please let me know if you want to keep drivers built-in instead of actually calling them via RPC.
In this case I will submit another PR - with the dependency version bump + the removal of checking the docker-machine-driver-parallels path, as it won't be used anymore.

I think this latter approach is going to be the better one. Feel free to open that PR and I'll review it.
