Add Sync with prune enabled in ArgoCD application sync

[saeedbibak]

The "Sync now" option currently exist in the applications section didn't prune the resources.

Thanks! This is being implemented in #769 (tracked in #712): a new "Sync with prune" item in the ArgoCD Application t menu that runs the sync with prune: true after a confirmation. Closing this discussion in favour of the issue and PR.
