[clearml-agent] Add Annotations to created Service Account

[dberkerdem]

Is your feature request related to a problem ?

We use GCPs Workload Identity feature to access GCS buckets from k8s workloads. To use this feature, kubernetes service account(k8s SA) must contain an annotation. So far we solved this issue by manually creating the k8s SA and linking it with the workloads using serviceExistingAccountName key.

Describe the solution you'd like.

Users should be able to add custom annotations to clearml-agents default service account.

Describe alternatives you've considered.
