Johan Thomsen 29bf511ef9 nixos/kubernetes: fix control-plane-online prestart dependency
The kubeconfig provided to the kubernetes-control-plane-online.service
is invalid. However, the apiserver /healthz endpoint can be accessed without auth so it's
simpler to just use curl for that.

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: 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.

nixos/kubernetes: major module refactor
- All kubernetes components have been seperated into different files
- All TLS-enabled ports have been deprecated and disabled by default
- EasyCert option added to support automatic cluster PKI-bootstrap
- RBAC has been enforced for all cluster components by default
- NixOS kubernetes test cases make use of easyCerts to setup PKI

Johan Thomsen 8d7ea96a13 nixos/kubernetes: improvements
- Added option 'cni.configDir' to allow for having CNI config outside of nix-store
  Existing behavior (writing verbatim CNI conf-files to nix-store) is still available.

- Removed unused option 'apiserver.publicAddress' and changed 'apiserver.address' to 'bindAddress'
  This conforms better to k8s docs and removes existing --bind-address hardcoding to 0.0.0.0

- Fixed c/p mistake in apiserver systemd unit description

- Updated 18.09 release notes to reflect changes to existing options
  And fixed some typos from previous PR

- Make docker images for Kubernetes Dashboard and kube-dns configurable

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

Ryan Mulligan b189247ba0 treewide: use more HTTPS URLs
Uses the HTTPS url for cases where the existing URL has a permanent
redirect. For each domain, at least one fixed derivation URL was
downloaded to test the domain is properly serving downloads.

Also fixes jbake source URL, which was broken.
