We change the default `--host-only-cidr` to `192.168.59.1/24` in order
to be compatible with the new default host-only networking restrictions
implemented in VirtualBox 6.1.28.
This fixes access denied errors on `minikube start` when using
VirtualBox >= 6.1.28:
```
VBoxManage: error: Code E_ACCESSDENIED (0x80070005) - Access denied (extended info not available)
VBoxManage: error: Context: "EnableStaticIPConfig(Bstr(pszIp).raw(), Bstr(pszNetmask).raw())" at line 242 of file VBoxManageHostonly.cpp
```
More details:
VirtualBox 6.1.28 introduced new restrictions on host-only networking:
https://www.virtualbox.org/wiki/Changelog-6.1#v28
Manual: https://www.virtualbox.org/manual/ch06.html#network_hostonly
> On Linux, Mac OS X and Solaris Oracle VM VirtualBox will only allow IP
> addresses in 192.68.56.0/21 range to be assigned to host-only
> adapters. For IPv6 only link-local addresses are allowed. If other
> ranges are desired, they can be enabled by creating
> /etc/vbox/networks.conf and specifying allowed ranges there. For
> example, to allow 10.0.0.0/8 and 192.168.0.0/16 IPv4 ranges as well as
> 2001::/64 range put the following lines into /etc/vbox/networks.conf:
>
> * 10.0.0.0/8 192.168.0.0/16
> * 2001::/64
>
> Lines starting with the hash # are ignored. Next example allows any
> addresses, effectively disabling range control:
>
> * 0.0.0.0/0 ::/0
These new restrictions manifest in the form of the following issue on
`minikube start` due to the default `--host-only-cidr` used by the
VirtualBox driver being `192.168.99.1/24`:

While the above is the primary error, other errors will be reported if
the adapter already exists (this happens when the adapter was created
before updating to VirtualBox 6.1.28, on a version of VirtualBox without
the new restrictions). Some examples:
```
❌ Exiting due to IF_VBOX_NOT_VISIBLE: Failed to start host: creating host: create: creating: Error setting up host only network on machine start: The host-only adapter we just created is not visible. This is a well known VirtualBox bug. You might want to uninstall it and reinstall at least version 5.0.12 that is is supposed to fix this issue
```
```
❌ minikube is unable to connect to the VM: dial tcp 192.168.99.112:22: i/o timeout
This is likely due to one of two reasons:
- VPN or firewall interference
- virtualbox network configuration issue
Suggested workarounds:
- Disable your local VPN or firewall software
- Configure your local VPN or firewall to allow access to 192.168.99.112
- Restart or reinstall virtualbox
- Use an alternative --vm-driver
- Use --force to override this connectivity check
❌ Exiting due to GUEST_PROVISION: Failed to validate network: dial tcp 192.168.99.112:22: i/o timeout
```
When switching to a valid CIDR, `minikube start` works as usual:
```console

👍 Starting control plane node minikube in cluster minikube

Having additional disks on the nodes is a requirement for developers
working on the storage components in Kubernetes. This commit adds the
extra-disks feature to the kvm2 driver.

This is the opposite command of "minikube image load",
and can be used after doing a "minikube image build".
The default is to save images in the cache, but it is
also possible to save to files or to standard output.
