The Cilium strict mode has a special mode which
loosens the security a slight bit. For compatability this
mode is enabled by default. But we don't need it for strict
node-to-node encryption. Therefore, we disable it.
The token given out by control-planes contains the node IP
as an endpoint. Since during this stage the joining node is
not connected to the WireGuard network, we cannot
communicate node-to-node. Therefore, we need to hop over the
load balancer again to have a src IP outside of the strict
range.
For the strict modes we need to dynamically use
the CIDR used in the Terraform files. Therefore,
we write them to our statefile and use them when
installing Cilium.
When enabling node-to-node encryption, Cilium does not
encrypt control-plane to control-plane traffic by
default since they say that they cannot gurantee that
the generated private key for a node is persisted across
reboots.
In Constellation we use stateful VMs which when rebooted
still have the cilium_wg0 interface containing the
private key.
Therefore, we can enable this type of encryption.

In unit tests, NewCollector may be called on systems that do not have
"journalctl" in $PATH.
We can defer checking if the command can work by not checking cmd.Err in
the constructor.

The unittest was flacky as testcases with valid certs
in the getter property lead to those certs being cached
inside the trust module. Other testcases however,
may want to explicitly use invalid certs. The cache
interferes with this.
