Allow to add custom permission on workflow service account role

[minzetaos]

Is your feature request related to a problem?

So far the workflow sa role only has access to workflowtaskresults. Think it might be better to make it more flexible allowing users to add extra permissions into the service account role.

Also prob worth having it here too: https://github.com/argoproj/argo-helm/blob/main/charts/argo-workflows/templates/controller/workflow-controller-cluster-roles.yaml

It seems I can't see pod logs because i can't add pod/logs permission if I use this created role here
