Update "parallels" driver library and make this driver built into minikube

[legal90]

Changes:

• Fixes Parallels driver is getting called as a built-in library instead of RPC Server #9493 . As we can see from go.mod, minikube is already shipped with parallels driver built-in. The requirement of having docker-machine-driver-parallels binary available on the user's host is not needed, since it's not actually used by minikube.

• Reverts Remove Init function from the parallels driver definition #9494 because it's the opposite (alternative) way of fixing the same issue.

• Fixes parallels: Your Mac host is not connected to Shared network. #9357. The updated dependency github.com/Parallels/docker-machine-parallels/v2 v2.0.1 includes the fix for macOS 11 BigSur. Ref: Improve the check if Shared network adapter is connected Parallels/docker-machine-parallels#96

Before this PR:

Make sure the docker-machine-driver-parallels is not available:

$ rm /usr/local/bin/docker-machine-driver-parallels
$ which docker-machine-driver-parallels
<empty response>

Then minikube requires user to install it:

$ minikube start --driver parallels
😄  minikube v1.14.0 on Darwin 10.15.7
    ▪ KUBECONFIG=/Users/legal/.kube/config
✨  Using the parallels driver based on existing profile

🤷  Exiting due to PROVIDER_PARALLELS_NOT_FOUND: The 'parallels' provider was not found: exec: "docker-machine-driver-parallels": executable file not found in $PATH
💡  Suggestion: Install docker-machine-driver-parallels
📘  Documentation: https://minikube.sigs.k8s.io/docs/reference/drivers/parallels/

After this PR:

Now the driver is built-in, so no additional action is required form user (as long as Parallels Desktop for Mac is installed and license is activated)

$ minikube start --driver parallels
😄  minikube v1.14.0 on Darwin 10.15.7
    ▪ KUBECONFIG=/Users/legal/.kube/config
✨  Using the parallels driver based on existing profile

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?

thank you for fixing it, I have no way of testing this myself but I trust you have tested this.

[medyagh]

do you mind putting the PR description the before and after this PR output ?

@medyagh Thanks you! Yes, I can add more details and provide "before" and "after" behavior later today.

But since you've merged #9494 I will also need to rebase this PR. Could you please tell me how do you want parallels driver to be called:

1. via RPC (as a standalone binary) ?
2. OR as a built-in library (similar to how it's done for virtualbox now) ?

[tstromberg]

I personally think that doing so built-in creates a better user experience, rather than forcing users to download a separate helper binary.

[tstromberg]

LGTM from my perspective.

@tstromberg @medyagh I rebased the branch, updated the PR title and description.

The idea is still the same - this PR makes parallels driver built-in, so no separate driver binary is required anymore (so that, it reverts #9494).
Also, it updates the driver to the latest version, which fixes #9357

[tstromberg]

Thank you!
