cfcc0898b2 helm: remove konnectivity from control-planes
This is the first step in our migration off of
konnectivity. Before node-to-node encryption
we used konnectivity to route some KubeAPI
to kubelet traffic over the pod network which then
would be encrypted.

Since we enabled node-to-node encryption this has no
security upsides anymore. Note that we still deploy
the konnectivity agents via helm and still have the
load balancer for konnectivity.

In the following releases we will remove both.

cac43a1dd0 ci: add e2e-upgrade test
The test is implemented as a go test.
It can be executed as a bazel target.
The general workflow is to setup a cluster,
point the test to the workspace in which to
find the kubeconfig and the constellation config
and specify a target image, k8s and
service version. The test will succeed
if it detects all target versions in the cluster
within the configured timeout.
The CI automates the above steps.
A separate workflow is introduced as there
are multiple input fields to the test.
Adding all of these to the manual e2e test
seemed confusing.

90b88e1cf9 kms: rename kms to keyservice
In the light of extending our eKMS support it will be helpful
to have a tighter use of the word "KMS".
KMS should refer to the actual component that manages keys.
The keyservice, also called KMS in the constellation code,
does not manage keys itself. It talks to a KMS backend,
which in turn does the actual key management.
