When a storage provider is enabled (storage-provisioner-glusterfile),
mark it "is-default" and set "is-default" to "false" in all other
StorageClasses.
There can only be one StorageClass be marked as default. When the
storage-provisioner-gluster addon is enabled, users expect it to be the
default StorageClass.
Instead of removing the "is-default" annotation from the other
StorageClasses, set it to "false". This leaves only the "glusterfile"
StorageClass as "is-default".
With this addon dynamic provisioning based on Gluster can be enabled:
$ minikube addons enable storage-provisioner-gluster
This will deploy several pods in a new 'storage-gluster' namespace:
- glusterfs, storage service with a 10GB sparse /srv/fake-disk.img
- heketi, a smart Gluster volume manager
- glusterfile-provisioner, external-storage provisioner
In addition, the StorageClass 'glusterfile' will be created. It is
currently not configured as default StorageClass, so PVCs need to refer
to the new StorageClass.
As per https://github.com/kubernetes/kubernetes/pull/32151, kubelet
doesn't search for CNI configs in /usr/libexec/kubernetes/kubelet-plugins/net/exec/
by default anymore.

Previously, minikube has been shipped with the default CNI config
(/etc/cni/net.d/k8s.conf) in its rootfs. This complicated a lot
when using a custom CNI plugin, as the default config was picked
by kubelet before the custom CNI plugin has installed its own CNI
config. So, the end result was that some Pods were attached to a
network defined in the default config, and some got managed by
the custom plugin.
This commit introduces the flag "--enable-default-cni" to
"minikube start" to trigger the provisioning of the default CNI
config.

Change the policy for the minikube-hostpath storage class addon from
Reconcile to EnsureExists. When it's set to reconcile, it's impossible
to change the default storage class in Minikube because it will keep
setting the minikube-hostpath storageclass to default.

* Change restart policy on gvisor pod
Change the restart policy on the gvisor pod to Always. This way, if a
user runs
minikube addons enable gvisor
minikube stop
minikube start
when the addon manager tries to restart the gvisor pod, it will be
restarted and gvisor will start running automatically. This PR also adds an
integration test for this functionality.
* Test stop and start
* Revert test to delete
Revert test to delete for now, for some reason "stop" and then "start"
is failing both locally and in Jenkins for VirtualBox with a "panic test
timed out after 30 min" error
This PR adds the code for enabling gvisor in minikube. It adds the pod
that will run when the addon is enabled, and the code for the image
which will run when this happens.
When gvisor is enabled, the pod will download runsc and the
gvisor-containerd-shim. It will replace the containerd config.toml and
restart containerd.
When gvisor is disabled, the pod will be deleted by the addon manager.
This will trigger a pre-stop hook which will revert the config.toml to
it's original state and restart containerd.
