Custom Annotations for Backup-Jobs

[sebschlue]

Summary

As a user of k8up backup operator, I would like to be able to specify custom annotations for backup jobs.

This would be useful to implement solution 1 as desribed in https://itnext.io/three-ways-to-use-linkerd-with-kubernetes-jobs-c12ccc6d4c7c

It would then be possible to have a job template like this:

jobTemplate:
  spec:
    template:
      metadata:
        annotations:
          linkerd.io/inject: disabled

Context

Please see https://itnext.io/three-ways-to-use-linkerd-with-kubernetes-jobs-c12ccc6d4c7c why this is important for users that also use linkerd and have auto-injection enabled at a namespace level.
