cli: remove helm management from join-config (#2251)
* Replace UpdateAttestationConfig with ApplyJoinConfig * Dont set up join-config over Helm, it is now only managed by our CLI directly during init and upgrade * Remove measurementSalt and attestationConfig parsing from helm, they were only needed for the JoinConfig * Add migration step to remove join-config from Helm management * Update attestation config trouble shooting tip --------- Signed-off-by: Daniel Weiße <dw@edgeless.systems>

During an upgrade with modified attestation config, a backup of the current configuration is stored in the `join-config-backup` config map in the `kube-system` namespace. To restore the old attestation config after a failed upgrade, you can copy the attestation config from this resource, put it in your configuration file and retry the upgrade.

During an upgrade with modified attestation config, a backup of the current configuration is stored in the `join-config` config map in the `kube-system` namespace under the `attestationConfig_backup` key. To restore the old attestation config after a failed upgrade, replace the value of `attestationConfig` with the value from `attestationConfig_backup`:
|
||||
|
||||
```bash
|
||||
kubectl patch configmaps -n kube-system join-config -p "{\"data\":{\"attestationConfig\":\"$(kubectl get configmaps -n kube-system join-config -o "jsonpath={.data.attestationConfig_backup}")\"}}"
|

```

You can use the `upgrade apply` command to change measurements of a running cluster:
|
||||
|
||||
1. Modify the `measurements` key in your local `constellation-conf.yaml` to the expected values.
