nixos/kubernetes: Stabilize services startup across machines
by adding targets and curl wait loops to services to ensure services
are not started before their depended services are reachable.

Extra targets cfssl-online.target and kube-apiserver-online.target
syncronize starts across machines and node-online.target ensures
docker is restarted and ready to deploy containers on after flannel
has discussed the network cidr with apiserver.

Since flannel needs to be started before addon-manager to configure
the docker interface, it has to have its own rbac bootstrap service.

The curl wait loops within the other services exists to ensure that when
starting the service it is able to do its work immediately without
clobbering the log about failing conditions.

By ensuring kubernetes.target is only reached after starting the
cluster it can be used in the tests as a wait condition.

In kube-certmgr-bootstrap mkdir is needed for it to not fail to start.

The following is the relevant part of systemctl list-dependencies

default.target

● ├─cfssl.service
● ├─docker.service
● ├─etcd.service
● ├─flannel.service

nixos/kubernetes: Add systemd path units
to protect services from crashing and clobbering the logs when
certificates are not in place yet and make sure services are activated
when certificates are ready.

To prevent errors similar to "kube-controller-manager.path: Failed to
enter waiting state: Too many open files"
fs.inotify.max_user_instances has to be increased.

nixos/kubernetes: let flannel use kubernetes as storage backend
+ isolate etcd on the master node by letting it listen only on loopback
+ enabling kubelet on master and taint master with NoSchedule

The reason for the latter is that flannel requires all nodes to be "registered"
in the cluster in order to setup the cluster network. This means that the
kubelet is needed even at nodes on which we don't plan to schedule anything.

Alberto Berti 0c841f98d0 Kubernetes tests: increase the size of the VM from 700MB to 1.5GB
VMs were starving, many of the daemons were unable to complete their
tasks resulting in tests failures.

Turned off verbose output from k8s components as it consumes even more resources, and useful error messages actually drown in debug-clutter

nixos: kubernetes fixes
* Fix reference CNI plugins
  * The plugins were split out of the upstream cni repo around version
    0.6.0

* Fix RBAC and DNS tests
  * Fix broken apiVersion fields
  * Change plugin linking to look in ${package}/bin rather than
    ${package.plugins}

* Initial work towards a working e2e test
  * Test still fails, but at least the expression evaluates now

Continues @srhb's work in #37199

Fixes #37199
