fix Error getting VM/Host IP address on clean install

[szabolcsdombi]

• replace getIPForInterface with VBoxManage equivalent
• network created by VirtualBox 6.1.6 is named differently then the adapter on Windows 10
• minikube v1.10.0 was failing to start due to net.InterfaceByName is failing inside getIPForInterface

Reproduce the error:

On a clean Windows 10 install with VirtualBox 6.1.6 the Host only adapter name is not matching the network name so net.InterfaceByName will fail due to the passed name is not an interface name.

Hi @cprogrammer1994. 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.

Temporary workaround:

go to the View Network Connections

rename
VirtualBox Host-Only Network #2
to
VirtualBox Host-Only Ethernet Adapter #2

if rename does not help take the name of the hostonlyadapter2 from the following command:

VboxManage.exe showvminfo minikube --machinereadable

...
hostonlyadapter2="VirtualBox Host-Only Ethernet Adapter #2"
...

@medyagh thank you for the quick resolution.
Due to my timezone I was not able to respond to your message in time.
It is great the fix did not have to wait.
Also great to hear v1.10.1 is out.

I will try v1.10.1 within a clean environment and get back with the results.

Thank you for this great project!
